I'm sorry you're feeling so lost.
Have you been to see a therapist about your aliens?
They do sound a little scarey.

Of course you miss your old girlfriend. There's nothing wrong with being nostalgic about it. You're lonely.
Why did you break up with her?
You've had a year and a half to heal from parting with her and maybe your meloncholy is a sign that you're ready to take a chance and find someone new.
Social situations can be confusing for me too. I think forcing yourself to talk to strangers, like cashiers and service workers, helps build confidence. If it goes wrong or it makes you feel wierd in anyway, the engagement is short enough to flee if neccessary.
You know, a lot of the cashiers are single women. It's worth a shot.
Who is this school person who you think will make fun of you and your aliens?
