I think getting therapy might help with this. A random person who doesn't know you, rejecting you, has absolutely NOTHING to do with your worthiness and value in this world. I don't doubt you feel this way and that sucks. However I think it's more a sign of a deeper self worth issue that can't be solved by someone dating you, and can be helped by getting psychological help.

For the record, I went to therapy myself, multiple times, in my life. I also went on meds for a time. So I am NOT saying this in any kind of negative way. I actually wrote an article called "Unconditional Self-Love" which goes into my experience with being ghosted by loved ones and how that affected my self esteem and how I recovered from that. I have not had the dating specific experiences you have found, but I have had my heart broken and my self esteem shattered before.
