Please relate. The “i want to die” thought?

I feel like there’s no way out of this. everyday i’m anxious and depressed from these thoughts. i feel like i have to constantly question if it’s OCD or not. the panic attacks are insane and i freak out. and a compulsion i have is looking eveything up on the internet when im stressing to know that it’s just my OCD and im not in danger. but looking things up add on to my thoughts and i start thinking “what if” actual suidcal people think. do others with this theme whenever they do something like if im taking a picture it’ll be like “yeah you look happy people will wonder what happened when your gone” LIKE i DO NOT want to end my life. or even as simple as cleaning my room, “yup keep it clean so when your family goes through your stuff” then i panic and can’t even do anything. those thoughts distress me so bad. i’ll sit there and think how good my life is or when im having a good day my thoughts will be like “NOPEEE what if your just saying that to convince yourself” it never shuts up and genuinely makes me think i have SI or something. i hope this reaches the right people just to know im not alone. Even when i do get better in the back of my mind it’s always “people who want to are the same a day before too” im genuinely scared and im scared one day im going to just snap and do it because its “too much” do i need to go to a mental hospital! i feel insane.

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.

the thoughts that have been making me super anxious recently is every-time I’m around someone im happy with my mind is like “they will miss you” or “they will wonder why you did it when your always happy” it’s eating me i hate it. i’m tired of this theme, it’s been on and off for three years. but it makes me more anxious now the it does before. please share tips
