Hi, it does sound like you have a lot to work through. I'm not sure what type of treatments there are like this, but if you have money I guess you could pay a professional to see you as many times as you like? Some only do once or twice a week, for the benefit of the client. But there's no harm in asking.

Also there is a person on this forum (I can't remember their name sorry!) Who sees their therapist for days at a time, eats meals with them, does loads of things with them. Maybe they have some helpful info for you about what this approach is called?
I hope you can find something that helps you soon
