I miss the feeling of safety

it feels like the fear i once knew it wasnt real now it is, it feels like i dont like him anymore and that i have changed. i am numb.

In the past I used to isolate myself when I was feeling bad or when my mental health became poor. now I feel like I don't want to be alone because I'm scared that when I'm alone, something bad will happen or i'll lose control and do something bad. And I feel like when I'm around someone e.g. my mom, it's easier to just let the thoughts go because at least there's someone there to verify that I haven't done anything bad.

I'm struggling with pocd it feels very real and I'm at a point where I feel I need to go to confess to the police stuff I know I haven't done but have false memories of doing and I feel like nobody thinks like this and very alone.
