I need help (TW hyoersexuality / past abuse)

Ok. I have an issue that did not only already ruin my reputation but also could make me end up in danger. I don't know why, but m*sturbation has become an issue. It wasn't an issue before. The last 3 days I basically did nothing but that out of compulsion. I neglected my health, my mental well being and obligations. What really scares me is that I think I'm developing some kind of perversion that has its roots in both abuse and prior porn addiction. As I said, it hadn't been an issue before, hadn't been for years. But now it ruins me. Worst of all, I was too loud once and I think my neighbors heard me. You can't even imagine how terrified I am of going outside. I have nothing left to eat but I'm too scared to go out by groceries cause my neighbors might see me. And I already have issues with social anxiety. Like, what if they'll file a sexual harassment case on me? I feel like a socially incompetent failure. It made me realize that I have unresolved issues. I need to change before my neighbors file a sexual harassment case and I end up in prison.
