Never think of yourself as wrong, invalid, defective or unworthy. That's wrong. Don't do it.
For about 90 % of my life I've thought about myself as defective in many ways.
- In puberty I thought I was defective because other boys were talking about their crushes, how they'd like to f--- this girl or that girl or how they got a boner just looking at them. Later almost everyone got a girlfriend or two. None of that happened for me, so I felt defective. Turns out I'm gay.
- Also in puberty I'd get random boners when sitting down in the bus. It made me feel ashamed and like a pervert, so I stopped sitting down in public transit. Turns out many boys experience this in puberty because, well... the vibrations. They're called "bus boners".
- I always struggled a lot remembering faces and names. I felt bad about it because I thought it meant I didn't care or try enough. I've always had issues forming relationships and again I felt bad and thought I just had to try harder and make a better effort, which didn't work. And various other issues, and for each of them I thought it was a defect of myself. Turns out I'm on the spectrum and my parents didn't bother telling me about being diagnosed as a child. I only found out when bored me stumbled over online autism tests and literally all of them came out strongly autistic-neurodivergent.
