I'm 44 and have only fairly recently been diagnosed with Asperger's... but I can relate to so much of what you said about school life and socializing... esp. dealing with the opposite sex...
I'd been variously diagnosed as having Bipolar, having Depression, all sorts of things, before someone hit the nail on the head... and have spent several years drugged up to the eyeballs on anti-depressents and anti-psychotics and God alone knows what else... i sure don't...
But now I am drug free and my mind is clearing and although I don't exactly see Asperger's as a blessing I do see that while I have limitations because of it in some areas there are also benefits too...
Yeah i have some pretty messed up habits and don't understand ppl well AT ALL... but a lot of that is learned behaviour and what has been learned can be RE-learned... in the right way now...
I was/am one of those poor sods who even had the Aspie gait... and that is not exactly a winner with the ladies I can tell you for free...

but even simple things like that - making a conscious effort to correct my gait, stance and posture - and remembering to do it and instead of beating myself with sticks when i catch myself 'forgeting' and 'schlumping' again but feeling good when i catch myself doing the right thing has given me the confidence to start on working on other behaviour patterns... It's gonna be a long slow road but already those around me have commented that they have seen a difference in me...
And like I said as an Aspie i can do things a lot of 'normal' ppl can't... while I can't manage a lot of social situations at all well I can grasp and readily understand concepts that elude others totally... My concentration is fairly shot as a result of years of un-neccessary 'drug therapy' but it is improving and I'm finding that i can stick with a project MUCH longer than those around me... they give up and come back to it later.... *shrugs* Some may not see it as a good thing but I do - i get 'fixated' and just put on another pot of coffee and finish the project...
You want to be a writer? Great... there is NO reason why an Aspie couldn't be... In fact there's some good reasons why an Aspie would make an EXCELLENT writer...
Aspie's seem to have good, active imaginations, we tend to be good with language (OK we mess up social interaction but we grasp other concepts easily and i for one really enjoy puns, playing with words, jokes of all sorts), we are single-minded when it comes to finishing things (well i certainly am)... These are all good points for a writer...
Whether you choose fiction, non-fiction, journalism, whatever... the lack of 'social skills' us Aspie's seem bogged down with needn't be a barrier as writing is a fairly solitary occupation and it would be a good way to explore social situations thru your writing.... eg By examining WHY ppl react a certain way in certain situations in your writing could be the very thing that helps you to 'fit in' better socially...
I'm a prolific writer... always have been... but never been paid for it... just do it because I enjoy it... I will write reams on a subject that i am passionate about... (Don't let anyone tell you that Aspie's don't have emotions... we have DEEPER emotions that others I believe... we just don't know how to express our own or react to/read others emotions is all - but like I aid that is a 'learned behaviour and as such can be RE-learned)
I hope that this all makes sense...
If you want to go into writing as a job/career man... MORE POWER TO YA!!!
Will certainly be praying that you achieve your goal...
