If you can't face people right now, then how do you intend not to be lonely? Would online interactions suffice? If so, this might be a good way. Wrong Planet definitely has its crap periods, but is ok much of the time.
I don't know much about human interactions, being the kind of autistic that doesn't need them, but I would also add that your post reads like you are wasting your caring nature on people who are not suitable. A caring person needs to be interacting with other caring people in my understanding - people who would never use you and drop you for their own gratification. Perhaps your loneliness is not your fault alone, or the fault of your autism, but also due to the fact that you have been wasting your energy on a***holes? Finding the right people who will treat you well may be in order.
