That makes me beyond fucking mad!!!!
NO, YOU ARE NOT A PROBLEM AND YOU DIDN'T START SHIT BY HAVING A HISTORY OF TRAUMA AND ABUSE.
Your behavior does not justify the way you were hurt or abused or treated. That's fucked and that mindset is not ok. You are not a problem, period.
As someone who has gone through abuse, I'm very passionate about this shit and I know that it messes with the way you view yourself and the way you think and you have the tendency to downplay it and deny it and when you finally come to terms with the fact that you were abused and hurt to have someone say you weren't....that's not ok. Not ok at all and I really hope this person or people fuck off because you deserve better.
