Hi there how2, I am sorry to hear of your experiences.
I wanted to respond to let you know that I was in a similar position to you around five years ago.
I initially sought therapy for depression but delving into the past brought back a lot of long pushed away trauma in relation to being sexually abused by a family member.
This time four years ago I was experiencing fairly severe cptsd and the main thing that helped for me was therapy, I went twice a week at my lowest points and did a lot of writing about everything.
It was unbearable at first, but I also found the strength to challenge my family about the abuse and neglect I experienced. I am no longer in touch with them and have spent the last few years rebuilding my life.
I will not deny that it was very, very hard at times. The first year after leaving therapy and going it alone was very difficult.
However, over the last 12 months things have really improved for me (ironically 2020 was a good year for me!)
I finally feel mentally recovered. I accept that there will always be parts of my experience that will leave a mark on me, for e.g I still struggle with executive functioning at times which I link with developmental trauma. However, I am kind to myself and treat those issues as though they were a condition like adhd or dyslexia - they are a part of me that I have strategies to manage.
I also had a complete career change and went back to Uni. Now I work with troubled children and that has been the most rewarding part of the whole experience. There is a concept called post traumatic growth and I definitely see my life experiences through that lens.
There was a time I used to dwell an awful lot on who I would have been without the abuse. Now I focus on who I am now.
That horrible, shameful feeling of being the odd one out has gone. Perhaps partly because of my job but I think mostly because I have processed all of what happens need to me and now I know I am just me, I am not what happened to me.
CSE is devastating, CSE from the people who are supposed to love and protect us is harder still.
I have every faith that you can recover, however, and it sounds as though you have already located good support to do this.
