Long time Reddit fan, first time posting!! Whoooohooo

I am graduating college in 2 weeks and I can't help but look back and wonder if I did it all wrong. When I first entered college, I immediately found a big friend group, and started a relationship. For the first year I was extremely happy with my life, I was going out a lot and constantly had plans. Now, three years later, I have had a lot of friendships dwindle. I ended up going through a nasty breakup with that guy and lost a lot of the connections I had before. I still have a few really close friends, however I somehow failed to make more friends throughout the years. I think I just get comfortable with what I have and I don't really push myself to meet new people. When I do find someone new that I could be friends with, I often struggle getting close to them. I genuinely think that I am an amazing friend but I am just not that person who can go out and make a bunch of friends all the time. Therefore, I am about to graduate and im feeling sad that I really can't say that I will have a lot of connections from college. The ones I did make are good, but there aren't that many. It seems like everyone else I know was able to find more friends and other friend groups and are still very socially active, and I am just feeling sad about how little of a social life I have now. I worry about this a lot as I feel like there is something wrong with me. Why is it so hard for me to casually find new people to hang out with? I can force myself to be extroverted, but it takes so much out of me and often I take it way too personally if that person does not show the same level of interest as I do. I have this huge fear that I will always struggle with this and constantly compare my social life to others. Does anyone else feel this way?

To add context, I have worked a lot on myself and have achieved a lot of personal goals in the past four years. I also got into a very healthy longterm relationship that is extremely fulfilling. So although I feel like a complete loser in one area of life, I am very proud of the other accomplishments I have made.
