I don’t agree with louise’s tone but I see where she’s coming from. David, if you feel that you may have inferiority feelings, I would suggest looking into yourself to find where they are strongest. Girls? Work? Family? Dig in and see what comes up. Inferiority feelings can make us intolerably withdrawn from the world and, unfortunately, this seems to be what has happened to you.
I know that often people go on forums because they have trouble with affording a therapist, but the right therapist could save you a ton of time. And you’d feel much happier. Do consider. If you are uncertain that you have inferiority feelings (or complex) maybe give this a read and consider visiting a therapist: https://theneuroscope.com
