I'm very sorry you feel this way, but I can absolutely relate. I made a lot of mistakes before I was properly taking care of my mental health. Embarrassing drunk and alcohol fueled hysterics in public, sexual escapades that every one knew of, naked photos, you name it and I ****ed it up. It's so important to try and put those things behind you, the fact you are feeling remorse for them (I didn't at the time) means you are a better person now. We can all be forgiven and if others can't see that then they aren't worth even thinking of their opinion!
