Wondering about this topic, I wouldn't say that if I was you. We are all good at something, we just need to develop and finally use it to show what we are good at. It took me 2 years to get good with .NET Programming in VB.Net.
Ever since I was young, I had learning difficulties and I was often weakened with knowledge at my starter years (Kindergarten, Prep etc...), so they took me to some special classes for tests. I'm sure by grade 3, I started to get better at my things and now I am in accelerated class doing Year 9 Maths in a Year 8 classroom, and I have to keep up with the standards. For some reason, some question that I'm a year older than them, but that is because of this. I try to make some other excuse, and I don't attempt to say out the truth. The point is, we are all good at something. If you despise this, there is no point saying out that you are good at something; you must believe and develop that skill.
I can try to teach you how to program, take some classes in drawing (probably Manga), take training and give out passion to that topic. Give years and soon develop skill and show to the public what you can do; the description should be reversed and you should do something about it. Also, have you considered programming, or JASS as such. Probably the knowledge side of things might suit your talents. Also, what Hawkwing said, ask for help when you need it. I'm sure others will be eager to help you, and you can probably learn from that. I have given you rep to start you off, should you reply and reconsider, or fail. Practice too, took me 2 years to develop some good programming skills in VB.Net.
