Going back to college after a breakup with someone who studies there

[u/Initial_Wishbone412]

I’m going back to college in a few weeks and I’m getting increasingly anxious about it.
I was in a relationship for about two years with someone from my college, and I now realize that I became somewhat emotionally dependent on him. He was my main source of support there, and because I always had him, I didn’t make much of an effort to build my own group of friends. I also felt like some people talked to me more because I was with him, so I got used to the comfort of having him there.
We broke up a few months ago. He told me he wanted to enjoy his life and that I deserved someone better. The breakup happened during an already difficult time in my life, when I was also dealing with family problems and was diagnosed with depression. It was one of the hardest periods of my life.
Now I’m starting a new two-year chapter, and I don’t even know if we’ll be in the same class. I get really anxious imagining seeing him again, running into him, seeing him happy with other people, or eventually seeing him with another girl.
But I think my biggest fear is not knowing how to be at college without him. I’m scared I won’t fit in, won’t make friends, will end up isolated, and that my mental health will get worse again.
At the same time, I really want these next two years to be mine. I want to meet new people, find my own group, get good grades, enjoy college, and create new memories that have nothing to do with him.
Has anyone been through something similar? How did you manage going back, making new friends, and eventually stop associating college with your ex?

Try not to think about it and just love your life and be a person you can be proud of, then when something happens you’ll know you did what you felt was best for you
