Unable To Love Me

… I just realized I have a longstanding belief that the people in my life aren’t capable of loving me. I think it felt helpful as a child – rather than I am not lovable, they are not capable. But now I have carried this thought over into relationships where people are capable of loving me and I am looking for things to support the belief that they are not. Not sure exactly my question. Just figured this out and looking for feedback on next step. I think I need some bridging thoughts because I objectively think they are capable but emotionally can’t rid myself of that old thought. Thanks!
