I do not think you have a learning disorder. Could it be from suffering for the past 10 years from depression.
I know that when i was depressed for over a year span it felt like my life was on hold.
I was actually always socially accepted in sports, prom court and bla bla bla. But when I was depressed I had no social skills. Gained tons of weight, was isolated and just did not even know how to talk, or how to or what to talk about with people. So i would let all of my calls go to voice mail. Would do nothing.
Anyways, I just think that you seem like a really cool person and that maybe you do worry a little-but thats so normal. Everyone has anxiety or nervousness. Some people that look like they never worry and like they have it all together--you'd be surprised by their story I'm sure.
It is hard to have a high self esteem when you worry a lot. I totally hear you on that. I just try to think to myself. Who cares what people think, and if they are not cool or understanding--there not worth having in my life then anyways.
SOrry I am rambling again. Also, when looking in those disorder books or the DSM...it is easy to categorize yourself in so many different disorders. Also, its easy to label others that you know too. I would say to try to not look at all those descriptions too much. Its good to be proactive but then what if you don't have a problem and your labeling yourself.
