I would really love to have people in my life but it never happens

Looking for advice… I’ve never figured out how to make friends. I’ve lived my life with strong working relationships at work, and at times I’ve had a partner or person I’m dating. I have kids as well. But I’ve never had a friend really… I mean kind of? Occasionally? But mostly not.

I don’t know what the secret handshake is really. It doesn’t seem to matter what I say or do or try, nothing makes any difference

Has anyone found anything that has helped
