I have no friends

I always text first and most of the time get ignored. Nobody invites me places but I invite someone somewhere at least once a month, but they usually cancel or only stay for maybe an hour. I’ve tried going out and meeting people, I’ve tried online. People just don’t like me. I’m 100% real and maybe that’s why? Someone I’ve talked to off and on for years who lives far away said they were gonna come see me and I was so happy for 2 days and then they made up an excuse and aren’t coming anymore. I should be used to it but it still crushes me every time someone cancels.
