41 year old autistic guy . I don't fit in!

I'm 41 years old, I'm functional and autistic.. yet, I don't fit in with anyone. I'm chubby, not exactly the best looking guy and I have a child like mentality ( the goofy and silly kind, not the tantrum kind) I have a huge imagination, that I get lost in, im clingy and need attention and affection. I love bunnies, NASCAR, pokemon and other random stuff, I used to be a truck driver (did that for 20 years), I have no kids, never married. I have no social life at all, preferring to stay home or spend time outside. I honestly feel like I will be alone forever ever, despite all my good traits.
