How to deal with trauma

So I was pretty badly abused and manipulated by my parents when I was younger and I just can’t seem to get past it. I’ve tried talking to a professional, I’ve tried talking to a friend, I’ve written it down and burned it to cleanse myself, I’ve done other cleansing rituals, but nothing seems to work. I’m just tired of being afraid of them all the time. I now hope that moving away will help, but I still have to wait months until I can actually move out unless I’m like super lucky and I find somewhere that I can move in now. Also to note, I have nowhere else to stay atm (no family or friends that has any space for me and my two cats).
