Hi and welcome, @loveconquersall , it's good to have you here.
I'm sorry to hear about your many traumas and your identity loss 😞
Something similar happened to me. I had to rebuild my life from scratch.
What I did was I started noticing things I liked, not things I had been told to like in the past. Even little things like certain colours, foods, etc. Also things I liked in life, such as reading and proofreading, things like that. I asked myself, what things gave me happiness, and always had maybe? Also things I had been told to like my whole life, and that I realised I actually didn't like. Also certain friends who actually dragged me down, etc. I acted on each little thing I realised. That way I started rebuilding myself slowly.
I am much happier now than I was in the first place. Much more the authentic 'me'.
The other thing that helped me was having a psychologist to talk things through with, and work through my traumas with. Do you have any professional support? Like a counsellor, meds, psychologist or psychiatrist?
If not, then the first step is to visit your GP and ask for a Mental Health Care Plan. This will entitle you to 10 subsidised sessions with a psychologist per year. The only thing is that psychologists are so overwhelmed with demand at the moment that it could take 6 months to get in to see one. But it's a good idea to get on the waiting list now.
You can help this process by googling then ringing round psychologists in your area to ask: are they taking new patients at the moment, what is the wait time for a new patient to start, what are the costs, etc. You can even ask if they are trauma-informed. Then you can take a name to your GP for the Mental Health Care Plan referral. (GPs might not know which psychologists are taking new patients and which have stopped as they are full.)
Good luck...
A handy forum tip is if you type @ and then click on a name in the drop-down box, that person will get a notification and won't miss your reply.
I hope you find the forums supportive.
