Hey there Hellion, I know how you feel, I'm on the Autism Spectrum too and find it extremely difficult connecting with others. I often like to think of myself as an observer of life, not an active participant (that would be everybody else around me basically). I have never "lived" in my life, so to speak.
I really feel for you, your mom sounds EXACTLY like my dad. I mean I'm 25 already but have the freedom of an 11 year old. I still live at home too, and I know the only way I would ever get out is to run away and live on the street. But actually I've considered living in the wilderness/bush, you know like some nomad, hunter-gatherer dude. What I really don't like is this modern money culture, everybody with some dough get treated like gods where I come from.
What can I say, damn, I'm 25, studying for my 4th degree on bank loans, living at home, no girlfriend because no woman in the world would ever be able to love me, got a car but can't drive very well (another thing my dad just forced me to buy), hopelessly fat but can't care enough to do diet and exercise (I would rather die than give up my Coke and junk food/chocolate), got an IQ of 150 but I'm the most moronic and stupidest human being alive when it comes to doing "normal" things, never had a job because no boss would want to employ a low down loser like me, and got no more passions or dreams or anything because massive depression just "ate" it all.
The thing I ask myself everyday is - what is the point of someone like me, why am I here? And, how the f*** did sh** get so messed up so damn quickly?
All the best to you, I feel your pain for sure and hope everything can work out the way you want, hopefully sooner rather than later. Many hugs

times 10.
