Hello Horus, welcome!
Personally, I think you need to tell your social worker about the voices too.
I know how embarrassing and uncomfortable that can be, but you need to make sure you're getting the help you need and deserve. You have to take care of yourself!
Months ago I had to tell my old therapist about some VERY embarrassing stuff, but in the end I was glad I did it because I felt like a weight was lifted off my chest and it helped me to sort out what was going on. My biggest piece of advice to you is whatever you do, DONT BOTTLE IT UP.
Bottling things up and keeping quiet does nothing but harm in the long run.
