Trying to Enjoy Being Single and Enjoying What I have

I have been single for about 10 years. My last relationship didn't end well but I don't have any regrets ending it with her. Since then, I have been dating/having sex with different girls. I don't have a big social network of friends like I use to since. My friends grew up by getting married, having kids, or just moved away. So I have been trying to keep my self busy.

Throughout my time being single, I have taken, dance classes, went to random trips, meet interesting people, go to the gym, concerts and other activities. I am trying to do anything to keep from thinking about living alone, short term relationships with women and not having any consistent friends. Thinking about it gets my angry and depression which eventually leads to me acting out. Eventually, I just have to focus on what I have, do major self care activities that doesn't always focus on needing women in my life.
