Wow, a lot of Aspies here.
I was diagnosed at nine. It made quite a lot of sense then because it explained my rather erratic behavior prior to it. I had very few friends in primary school, they tended to come and go when they got sick of me, and I did get bullied a lot. That doesn't bother me any more because those guys were idiots, and it's only made me thick-skinned, though I haven't experienced bullying for several years.
When I was a kid the most obvious feature was the narrow intense interests; cars, trains, planes, dinosaurs, all of which remain to some degree, but are not my primary interests. A fascination with skyscrapers hit me after 9/11, and that one caught a lot of people's attention, I didn't help that I tended to rant on and on without stopping!
I didn't necessarily mind not having many friends in primary school, I was happy to entertain myself and be off in my own world.
Things got a bit more difficult in secondary school. Virtually all my primary school friends abandoned me, and I ended up in a small group that involved me and someone else fighting for the attention for another. I was doing it because of, what seemed like an attraction at the time, and I think the other guy was too. I realize now that what I was experiencing was probably an extreme desire for friendship that manifested itself as sexual attraction. Even so, me and this guy were best friends for about three years, until he got caught up with drugees and basically ruined his life, these days we're still perfectly good friends, though we don't see each other every so often. We eventually assimilated into a peer group of about 30, and from that I have current 'wolf pack' of five.
When I started cello in Year 10 I was able to channel my compulsive nature into something useful, it's got me a performance diploma, into uni, and on stage at the Royal Albert Hall, all in less than five years.
These days the biggest effect Asperger's has on me is OCD. I have a sometimes crippling fear of disease and germs, which I've had for about 4 years now. It comes and goes, but I can control it relatively well. I also need to control my immediately environment and have a plan or routine that stays fixed. I've never received any formal treatment or medication for AS, I've to basically had sort it out myself. I've learnt from my mistakes, and I have a very supportive family and a secure and close-knit peer group. These days I don't think I'm suppressing it anymore, but it just is what it is. It'll probably never go completely away, but I think it will just continue to dwindle.
