Reddit is a fucking hellscape

Idk anymore it feels like being on here is a trigger. Every time I see a minor post on the app, my intrusive thoughts go haywire and then my brain says maybe you should comment something inappropriate and i literally don't wanna fucking do that. It's the last thing I want to do. And now im scared that I commented something crude on someone's post. obviously, when I went to check there was nothing now my brain is saying "you commented and then deleted". I want to think it's something I wouldn't do, but why are the images in my head so real. Children should be safe. I feel like I need to be locked away. Someone please help me.

I posted a comment on a video on tiktok and got super super attacked by it and it’s making me feel like I deserve to go to hell because I typed it wrong. The context of the video is that basically this girl is saying she’s never met a genuinely non judgmental Christian and I said:”Every single time I mention not waiting for marriage with my boyfriend I’m suddenly scolded and shoved with all the benefits of waiting down my throat. It honestly drives me further away from Christ” and people were reading it my boyfriend was the one shoving the benefits down my throat when that isn’t the case at all. My boyfriend does not claim to be a Christian. He is discovering his beliefs as am I as a semi-Christian still figuring things out for myself. I meant this comment as other Christian’s scolding me for not knowing if I want to wait and it driving me further from Christ. But one of the comments said this: “these are non negotiables if you’re a follower of Christ. He’s standing firm in his convictions, if you’re unequally yoked in faith the relationship will not work. You know his convictions, you know his Faith, yet you’re pushing him into temptation and sin that’s clearly defined in scripture. That’s being disrespectful to him and his faith. If you’re not on the same page on such a crucial thing, it’s okay to not be with him.” And a couple more comment such as this. This was SUPER triggering for me. I eventually commented back saying that wasn’t how I meant the comment and should’ve worded it better, but now I feel like I have to be miserable with Christ and follow everything they said and break up with my boyfriend because this person said I’m like horrible for shoving it down his throat when that isn’t the case. What if I’m a horrible person and deserve eternal damnation and just don’t know it. What if I’m secretly like a demonic creature that is ruining everyone’s lives and just don’t know it? I’m so scared for my future and that everyone hates me now

Been off this app for 2 years. Now I’m back with a terrible theme of getting cancer and dying. I can’t sleep, can barely eat, and think about it constantly. I’ve posted on Reddit to alleviate stress, but nothing works. I will die regardless and no one can assure me I won’t get cancer. I just want to stop worrying and feeling so scared all the time. I’m a med student and I want to drop out because I don’t think I can handle seeing people sick and not assuming it’ll happen to me
