Therapy?

How do I get Diagnosed? And is any therapist adequate to dealing with OCD?

I am typing as I sit on the couch after a mental breakdown due to the frustration and fear I have with my Suicidal OCD intrusive thoughts. I know so much about why this is happening from therapy, research, and self help books that I feel like knowing this much about my condition is almost making it harder to recover. It’s like I feel like since I logically understand my problem, why can’t I change my response to it? I know logically that these thoughts are stuck in a loop because I have assigned meaning to them and am so scared of the concept of harming myself, yet ERP/CBT hasn’t yet helped much with my ability to tolerate the anxiety. I have moments where I feel good but the sense of impending doom and feeling like I “am bound to hurt myself” always comes back. At least for the last 2-3 months since this theme and OCD flare started. I don’t have any physical compulsions that me or my therapist have been able to identify except *maybe* researching too much. But other than that, my compulsions are all mental. However, I can’t pinpoint what exactly they are. It’s also important to note that I don’t avoid anything. I still use knives when I need to, I don’t hide them like others with this theme do. Yes they can trigger anxiety but I don’t actively avoid them or other items that trigger/have potential to harm me. When I do audio exposures (listening to my voice saying I am going to hurt myself), I hold a knife to my wrist to intensify the ERP, per my therapists request… and still the same or similar level of fear behind suicidal and harm OCD thoughts is there. Has anyone dealt with this and can help provide some insight as to what helped you? Anything is helpful here except negativity.

How do you go about your life when ERP therapy is so stressful. I have harm ocd and by making me watch horror movies etc . is just making it worse. I'm really worried I'm being brainwashed into being what I dont want to be . Does this mean ERP is not for me? I also have no compulsions just pure O .
