I'm 32 now and met some of my current best friends when I was 26. My parents are 60 and just moved to a new country and within a year they met a dozen new people they now hang out with all the time.

It sounds cliche but it's literally true that there's always time to meet new people no matter what phase of life you're in.

Related: when I was 25 I had a depressive existential crisis and felt like my life was basically over. It's common, and therapy was a lifesaver. If you feel like you might be depressed then talking to someone can really help. Take care of yourself as best you can!
