Insomnia and OCD?

At times, my intrusive thoughts get so intense that all I can do is lay frozen in my bed and hope I fall asleep, and usually I do even if I'm not tired. My brain just wears me out and I wanna escape through sleep. (Sadly it doesn't work all the time)

Does anyone have any advice on how to deal with intrusive thoughts&images. At first i had intrusive thoughts around my partner, now it’s centred around me & I can’t be around window ledges or medication due to a story I read online(it’s too triggering for me) . Sometimes I feel like I can’t leave my bed due to the thoughts being so overwhelming I just break down and want to sleep. I aren’t taking any medication or therapy yet. I worry that if I don’t give my thoughts a reaction that my thoughts are true and not OCD. I’ve had these thoughts 24/7 for 2 months.

so I need to get back into ERP, but it’s so hard to manage these thoughts and learn to deal with them. like I swear my mind has to make everything about it. Like every time I clean my room, my mind’s like yup make sure it’s clean so when your parents find you, or something so stupid like if I get a headache, my mind convinces me that I like the pain and that that’s why I get my thoughts because I actually want to do it. It’s so exhausting. Because I know I would never want to take my life and I treasure my life so why does it do it to me? It’s hard to comprehend the fact of these thoughts too because I don’t know many people with this exact theme. It’s such a scary feeling. And I’m constantly questioning whether I have actual depression or if it’s just my OCD. Yes I have been diagnosed with suicidal OCD, but my mind still tries to convince me otherwise. I just don’t know how to let these just sit and pass without panicking.
