I wanna stop using my phone a lot because it causes me eye strain and headaches but it's an addiction I wanna stop but I don't kbow how and I'm scared I'll go crazy with out it

I don't know what to do anymore, the fear of psychosis and schizophrenia is so bad in so hyper aware of everything I hear and everything I see, I've always had eye floaters now I convince myself that it's really me hallucinating, I've always had tinnitus but now I'm convinced it means I'm going to go crazy soon, I can't sit in quiet because all I'm focusing on is what I'm hearing, and searching for any sounds I can't distinguish, when there's background noise I get so anxious if I think I heard something but im not sure I did or I'm just anxious, I'm terrified I'll start having delusions and sometimes my brain confuses some sounds for other sounds for example say I'm hyper focused and I breathe and my nose makes a whistling sound my mind interprets it as a scream and I freak out thinking I'm hallucinating only to focus closer and realize it's my own breathing, earlier I was so anxious that I couldnt tell if I had an intrusive thought or heard something, I don't know how to make it stop, I've been through this theme before I just forgot how hard it was I'm having a panic attack please help

Finding this app has helped me a lot in feeling like I'm not isolated and I've definitely met so many kind and helpful people here. You guys have helped me on my darkest days. However, because of my fragile state of mind, I think scrolling on here is becoming a compulsion and I feel like I end up triggering myself more by scrolling through some posts. I think it just ends up adding more to my intrusive thoughts and more ammo for my false memories and POCD to latch on to. And I know exposures are good for treating OCD, but this level of exposure seems to be doing more harm than good. So I will try to be less active (maybe I won't, who knows lol).

I’m so stressed, my mind is always telling me to recheck my messages that I sent because what if I said something racist, inappropriate or mean to the person I was messaging. Or what if I post something inappropriate or rude, the only way I can somewhat cope is by logging out of my socials every night. But even that is a long progress. Like I have to make sure to read every message I sent and that it’s safe for me to leave it for the night. And if it doesn’t feel right I have to log back in over and over until it looks and feels good to me. I’m so exhausted lol:,)
