I resonate deeply with you that. I kind of had a similar attitude like that growing up, but each time I fought back it kind of rubbed people in the wrong way, and being ugly itself oozes out an unpleasant aura (to not want to be around).
I guess its understandable knowing that you feel like the whole worlds against you, but then you have nothing left to defend for yourself, and knowing that hardly anyone will be there for you. Women already have the luxury to not feel this pain and as they have a lot of support groups, friends around to keep themselves safe.
What helps me with my knee pain is doing single legged bulgurian split squats, don't squat to deep, just squat where the knee is about to hurt, and of course, its going to take time to heal of course.
