Hello HappyTauren, didn't see your input at all. Sorry.
There are a few things we should discuss, since you are too sensitive with this matter.
First off, don't blame your parents. They sometimes exaggerate, in their trial of being protective. This is their job, this is their instict. Once somebody becomes a parent, they develop insticts, we, the younger ones, can't realize until we become.
Secondly, realize where you stand, your environment, your social contradictions, yourself. You are at the age of 16, you are in the middle adolescense. I know, how boring it can be, listening to the same phrase all the time: "You are very young", while you need someone, apart from yourself, to claim the exact opposite. Being mature isn't a factor of age, it is a factor of incoming experiences. Every experience you claim, will make you more mature. So, your wish of being 18 wouldn't be an excuse to make whatever you want. Your words express hatred against your parents. Remember, they are the ones who raised you with love and everything required, else, you wouldn't live.
Apparently, you are too young to be grateful, and if you admit the opposite, just check your words. I am almost 20 and I go back in time, back to the way I was thinking in the age of 16 and I swear I can't compare myself now to what I was.
It is obvious that you have entered an emotional phase every adolescent goes through. Not much can be done here, since this rebellion is based off hormones. Just try to realize that, because you express anger or attain effects of your own, doesn't mean that people are against you, but it's the fact that you are living in your own world, which you are about to compromise or get it engulfed within the adults' one, once you grow up a little bit.
You now consider yourself as a seperate being, one that wants and tries not to be dependant on others, especially your parents. Respected and comprehensible. Can you afford being alone though? You are even afraid of talking to your friends; instead of insulting them, try to figure out if the actions or the thoughts of yours are considered flippant.
You might think I am speaking in a very generic way, but I am trying not to focus on this issue alone, since your thoughts, feelings and actions belong in a much wider dimension.
Let's now focus on the issue of yours. I won't relieve your current pain, neither will support you, but I will try to show you how to react realistically.
1) Apparently, distance is a factor that can ruin a relationship. You are not in this state, but you would likely be. Avoid selfish thoughts of "Me, myself and I", because they will help no one, especially when you are trying to achieve something. Fortunately or not, your parents' speech is way more effective (and justly) in the family, so, if you become selfish, their first action is becoming selfish as well. Try to be logical-thinking/-acting. Your parents will admit they have a mature child. If your parent(s) have a problem, stand next to them and try to help them. State that you can be their assistance. If you want to be treated as a "grown up" person, start acting like them. Don't resist too much, when they are asking for favours; instead, start having small talks with them, start showing them how easy it is for you now, in this age, to become a member of their conversations. Like CMarket stated, communication is a saviour in most of occasions. In the current state, stop mentioning this girl. Let them just realize you keep having contact with her and state nothing more.
2) Patience is a virtue. I won't make your dreams come true, like I said, so, if you want to work this out, just wait. What can you expect from a wait? Either develop greater feelings towards this girl or let the memory of her fade. You can see that your parents' voice is everywhere. The first is your voice, the second "either" is theirs. That's ourself: a piece of us contains everything we deposited through religion, parental advice, beliefs and social affections. This is how we get ourselves complete. You can wait for vacations (not family ones, e.g. Christmas, cause I can predict the reaction of your parents: "NO!"), like summer holidays, in order to get in touch with this girl again. This is a test for you and her, on whether this relationship is going to endure or not.
3) Philosophize it/ Make a paperwork of yes' and no's. The best way to not be so emotionally attached towards a specific event is to consider every aspect of it. Get a piece of paper and make a small list of questions, ones that you would hardly answer yourself. Place three options "Yes"/"No"/"Explain". The questions must contain personal data that you avoid thinking of. If you see yourself inspired enough, I would higly recommend using the "Explain" answer as well, where you are supposed to write emotions down. This will help you express how you feel. The questionnaire should contain questions, concerning yourself, your parents, your friends, your emotions over this girl, everyone involved with this matter. (This technique can be used on every problem of yours) A question-type you could use is: "What will happen if the communication between me and her doesn't endure?"/ "What if she accepts the distance factor and move on with another guy?"/"What do I like on her?"/"Do I like her?". Sum up the results and make a view of yourself.
4) Similar to 3), use a list of statements with the options "How would I feel"/ "How my parents would feel". The statements are everything that are currently concerning you. Fill the answers with the "How would I feel" option and the "How would they feel" option, guessing what the reaction of your parents would be on each statement. Then, take the list and show it to them. Explain how you feel and what made you think they would react that way. A healthy conversation will start.
5) Ask a photo of this girl to have on your computer. Present it to your parents. They will start getting themselves familiar with her presence and make them more interested over this "what's-up-with-this-girl".
6) Give them a movie to watch, while you hang out with your friend. The movie's theme will be your life's current state: Love from distant places, with a factor of national feuds. Try a very touching one.
7) We started the steps with communication, I close the steps with communication, to highlight its importance. After getting effect over this, if your direction is to follow your heart, you would want to explain how national feuds have nothing to do with it. Explain that each person is a single personality and not bound to the beliefs or religional aspects. Let them know that, because this sounds strange to them or haven't dealt with such issue before, it doesn't mean that it doesn't deserve giving it a try. Have them by your side, not as your enemies. Respect their view, let them know your own without any quarrels. The statements' test of "My view" / "Their view" is a great way to depict the chaos between your beliefs. In the end, explain that the national feuds should not keep people chained and that this issue is a silly government's issue, not yours. Apparently, love can meet no boundaries. Don't be too love-blown, because they will undervalue your feelings and speech; remember, you must be logical acting and talking, that is the key to win.
Good luck.

And while being informative and making small talk is easy with my fellow juniors, I'll look into the possibility of 'opening up' more towards the more coy seniors, thanks. (Don't like the idea of 'opening up' to them tho) Anyway I'm in a long-distance relationship, and bringing another girl into the picture might be cool, I guess.. but this little problem is merely on a 'perplexing' level now. When it gets to 'desperate' then I'll start thinking about involving other people into it. Thanks again here.
