<human>: I've only had one girlfriend, who is now my ex, which took me about a year to get with her. We were best friends but now we're not friends anymore -  I guess we were better off as friends. 

There wasn't anyone so nice like her, who was so accepting of me, and she was also the first real female friend of mine I've ever got close with.

Anyways, she's out of my life except when I do see her in the hallways in college. But I decided to go into this Spring Semester all fresh, with an open mind, trying to be the most outgoing and optimistic person, as if I was an actor.

But I feel like I need to stabilize myself emotionally to prevent myself from having neurotic thoughts or mental breakdowns just from seeing her alone, or with someone else. I need to get into the dating scene, like I need to play the fields and find the one. I'm 18 and I'm scared to shit that if I keep stalling for the next few years, I'll die alone as a virgin. 

The problem with me is that I'm socially awkward, I have a different sense of humor, I don't understand jokes people say, I can't laugh, and I get bored easily. Also, I'm scared to just talk to a girl, especially girls that have a lot of friends. I'm scared to talk to girls in front of all their friends.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Need to get into dating again in order to fully move on from my ex, and I just want to get more experience with girls.
