Have you guys had a change of personality? Because what the actual fuck happened to me?

 used to be an extrovert, but this year, connecting was hard for me. I used to collect friends like Pokémons, always. I always was surrounded with people. loved meeting people and making friends and just being surrounded by different personalities. I never really understood the fear of being alone because there was always someone I wanted to talk to. But recently things changed, I have barely interacted with new people.  I've kept people at a distance, intentionally or not, idk. And I love it and hate it at the same time. I loved this feeling of being alone, having my own space and not having to constantly engage. But I also wanted conversations to go on for hours and stupid jokes and people with whom I could share most random parts of my day with at the same time. And I generally cannot figure out where I stand anymore. What worries me is I want my college years to be with friendships and people. I love the idea of finding my people. I'm just scared if I carry this part of myself into uni. so accustomed to keeping people at a distance that I don't know how to let them in anymore. I don't know if I'm overthinking, or it's just a phase, or wtv. I just hope I haven't lost the part that used to connect with people comfortably. Because, hell. Also recently it's, like, I've been getting awkward a lot and I never used to be!
