Existential OCD/ Derealisation

I'm adding a trigger warning for those with Health OCD and Existential OCD, just to be safe! The past week, I've been experiencing a lot of déjà vu. I'll post something and immediately feel a strong sense of familiarity, like I've done it before. It's been happening so often, I'm questioning if I am actually repeating things and not noticing, but then there's obvious moments, like phoning my dad for help fixing my pc that can't be replicated. Then, just before writing this post, I'd been thinking about going on a walk, and I got déjà vu having that thought. After, I felt this strange impending doom? Like, if I go on the walk, I'm going to get kidnapped, or something bad is going to happen to me. I'm not sure what this is. I'm not super freaked out, just curious and keeping track of how often it's happening... I'm still going to go on that walk, though, because I feel like if I don't, it'll feed into this fear I have.

So this past week I’ve had a really bad ocd spiral. I can’t stop thinking about death and what happens after. Because of this, I’ve felt no motivation to get out of bed. I don’t know if it’s burnout from school, depression, or just existential ocd. I can’t focus on the present,and I feel like I’m in a dream like state. I went through a similar time a few years ago, and was able to get out of it. Even if I do accept that death is inevitable, how do I get motivation to do anything when I know it won’t matter in the end? Any tips?

Hey guys so I’m new here and just recently started struggling with some health ocd and thinking I had a brain tumor but it’s taken a turn for the worse and become this existential ocd where I’m questioning quite literally everything in my life, the purpose of being here and stuff. I just started meds yesterday, which is scary for me cause I’ve never been on them before. I keep having thoughts like, why does everything feel like a blur, what’s the meaning of this and I wake up every day with just existential dread. I’ve been having very vivid dreams that make dreaming and reality confusing I also am scared cause I’m dealing with some DP/DR as well. I just wish my life could go back to a few months ago before I knew all of this was possible. I guess I’m just writing this too get it off my chest and see if any of you all have gone through something similar and made it out okay?
