Hey Noodle,
I've been exactly where you're at. It's really hard on you to make sense of things and to fit in like yourself. I lost my ability to fake it when I became overwhelmed with my kids. I'm now on medication and I have to say it has made a world of difference. I know I'm different, but I can say I like me. I think that's where people pick up the depressed vibe. I don't think I was depressed, just really confused.
Knowledge of AS helped alot, know your differences and don't apologize for them. My son has more strengths than weaknesses because of Autism, some people have more weaknesses, but we're all there. My take is everyone is on the spectrum....everyone, some are just further along. I like thinking there are more people like me. I don't feel lonely. Look for support groups in your area, I tried that but couldn't find any in my neighborhood. I might start something but I think I need more help from NTs right now than other ASs. This place has been great, hang around here and you'll find all kinds of support and help.
Good Luck
