Hearing you @The-red-centaur .....
You don’t have to report it to the police. If it’s too heavy a load for your mental health to do that, then just say no, it’s too much for you to be able to do that, and leave it there.
If you change your mind at some later date and want to go to the police, you should still be able to do that. Your case worker can find out for you if you want.
It’s an upsetting situation, so do what you believe is best for you, according to how you feel now.
And keep looking after you .... what sort of self-care activities can you do tonight ?
