Hi @Tigga321 - @Faith-and-Hope mentioned you in another thread. I have come over here to welcome you and introduce myself.
I know a bit about about being abused as I suffered at the hands of my former partner. I eventually escaped that relationship but understand your feelings of helplessness and worthlessness.
I went to therapy sessions and found them only mildly beneficial. What really helped was meditation through yoga and walking whilst listening to music and with my dog. I also got my body in really good form (until i shattered my arm - but that's a whole other story)
It was my way of empowering myself. When I had bad thoughts and dreams - I told myself that I was safe and put up a virtual shield. Eventually those flashbacks became fewer and fewer. You won't forget but hopefully your reaction will be less frightening.
It sounds like you could use some friends. You have probably found this forum to be a very caring and nurturing place. If you are selective where you go, it can be a wonderful place to hang out. Sometimes you may need a break and that's okay too. Just know that someone is here ready and willing to listen and just be with you if that is what you need.
