<human>: Freshman year, and the first semester of sophomore year were the best times at college. I was incredibly social, and was able to talk to anyone without hesitation. I met and befriended girls, got their numbers, had regular sex, and had an absolute blast. Entering my first serious relationship led me to change this lifestyle. She became my social life, I never worried about my physical health because I was already in a relationship, and failed to maintain contact with most of the people I met up to that point. 

Fast forward a year, to the present. After breaking up, I have noticed that being social is a serious struggle. I am not confident around others, even around my closest friends. I'm not even confident in what I say, because I am very conscious of the major social change. My voice is weak and shaky, and I even stutter. When the hell did that start?! The ease of social interaction has left me, and I feel excluded from the groups I used to be a major part of. 

I know that it's normal to lose contact with everyone when in a relationship, but I was not expecting the loss of sociability. 

How can I get it back, and have it become second-nature once more?

I'll address a potential point:* Why do you want to go back to the person you were? You should become better and more than you were..."*

I would accept that, if what I had become weren't so much worse than what I was before. I liked the person that I used to be, and people enjoyed being around that person. Now I can tell that people aren't as invested when they are around me. Conversations are incredibly short, and never personal. It just became a huge domino effect, and the first domino was noticing that change. The more I thought about it, the more I noticed it. This could be interpreted as a self-fulfilling prophecy, I know.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I used to be a social butterfly. Entered into a year long relationship, broke up, and instantly realized that I had become incredibly antisocial, and the ease was gone. Lost contact with most of the people I met.
