Thunder Bow has made a valid point. In the meantime you have to do some soul searching and be at ease in your own company. Go to a coffee shop and people watch just let world roll by.
I would try and forget about the link between social skills and aspergers. The last thing u need if your down is to find out something is "wrong" with you.
I've been through spells of being alone as in not a friend in sight. The thing is I thought I may have been a schizoid or have a schizo typal personality. But I'm just ordinary schizophrenic n bipolar. It was underlying my whole life but didn't explain everything.
When I was in psyche ward a nurse told me I had an attitude problem and that I was arrogant. It was a defence mechanism .
Back to you. I think you should contact a GP and say your crying all the time this indicates depression. Sometimes a person can get by with just enough contact from others, more acquaintances than friends and one day some part of us just awakens and we realise we've been missing out. Then we have to stop the regret setting in and find out why we lived way we did and managed on our own. Having a therapist to confide in isn't a sign of weakness
