I have ptsd from getting sexually assaulted when i was 11 my mother thinks my ptsd is a sign of weakness and not being over the past is that true?

No, it is a really challenging problem to most people, not because of your weakness. However, you will overcome it eventually with counseling and with your will.

PTSD is a disorder and not result of mental failing. Do seek counseling for your disorder. Sometimes medication can benefit a person. Get HPV, Flu and Covid vaccines. Wish you good health!
