Anyone else have a general feeling of dread?

With real event OCD, I don’t know if any of you feel this way, but do you ever feel that the past event(s) that you ruminate about or constantly obsess about are gonna come up in your future and just absolutely ruin you, that’s how I’ve been feeling for months, it just feels like impending doom, and I hate having to even think that my future would be ruined by what I did as a teenager, and I did some dumb things, that I regret so deeply, I just can’t stop thinking about that.

I don't know if this is exactly a compulsion, but for a few months I had this mindset of "I have to be anxious so that nothing bad will happen." It was mostly when I went out in any way. Sometimes it was for other people too. For example if my mom went to the store/to get food without me. This was mostly during the time when I had been staying inside constantly for a little over a month. Idk if it was an exact cause but I had seen someone who FOLLOWED me last year, hence why I was staying inside. I guess I just want to know if this is common? I know that the whole "if I do this, then this won't happen" thing is common in ocd, but idk how common it is to somewhat force yourself to be anxious.

My OCD has bounced around to a lot of different topics but my current spiral has been focused on existential dread - I have a lot of intrusive thoughts about my loved ones dying and not existing and about my own death and not existing anymore. OCD is trying to get me to find certainty in what happens after we die… and unfortunately I will NEVER be able to find certainty around this. This spiral started after the death of my beloved cat and then the almost death of my dog a week later. I think OCD attached to this idea that everyone and everything I love is going to die and I need to prepare myself for it and somehow KNOW what happens when someone dies. It’s panic inducing and really hard for me to sit with vs other OCD themes Ive had related to health, moral/hyper responsibility, etc. Anyone have this type of obsession around death of loved ones and how did you combat the intrusive thoughts and deal with the mental compulsions (rumination, avoidance, etc)?
