Thanks for this. I have been diagnosed with PTSD but I was beaten up on daily basis by my younger sister. She constantly beat me up or threatened to hurt me. I grew up feeling inadequate as a boy and have had very low self confidence and have a number of mental health issues and have been in and out of therapy since my 20s. My family didn’t protect me and called me sissy or wuss for not being able to stand up my grounds, which added to my problems. Because of the low self esteem caused by my sister, I was bullied at school as well.
