Am I hopeless? Should I even bother?

I'm 49. I'll be 50 in a few months. I haven't had much luck with women. I've only been in 3 relationships my whole life and they were all toxic. I can't even approach women because of social anxiety. Online dating I get nothing but catfish. Should I just give up and accept that I'll die alone? Because I'm tired of trying.
