I have Level 1 Mild Autism. This means I can still do things independently. However I suck at talking and making friends. Or saying the right things to others. I've never been popular and liked during school, as I mainly spent time by myself and preferred to 'draw' and 'talk' to characters I made up for example. People would find me weird and boring and too many times I'm misunderstood. When I've confused, pissed off, upset or frustrated someone because I/they couldn't understand what I've tried to say/want.
Autism is different in everyone, so my experiences may be different from yours. When you're talking about 'some parts', can you please explain a bit more about this?
I want to say though that you are not alone, and there are many people who have Autism and feel just as equally alienated from society as I am. Let me know what you think.
