I know how you feel. I'm 35 years old, no close friends, and I haven't had a boyfriend since I was 21 years old. I think at our age it's difficult to make friends especially if you're like me and have social anxiety. I personally think the best way to meet people is to find a hobby you like and do that (a meetup group is a good way to do this). You'll meet like minded people with the same interest as you, so you'll have that in common to conversate about. Another option, which I'm considering to do, is volunteering. I've read that volunteering significantly reduces depression because you get this high from helping others. At the same time, you'll meet other people and probably make friends (and it won't feel as forced as a meet up group)
