My ocd theme is currently centered around the extreme fear of my boyfriend or a loved one dying ?

Hi all, I’m F(20) and I’ve been in a relationship with my boyfriend M(20) for 10 months now. Lately it feels like I’ve been getting triggered at the tiniest thing. My relationship OCD is centered around the idea that my bf will leave me, that suddenly his feelings will change and he’ll never look back. Inherently I know this is irrational and I know he loves me very much (as he tells me repeatedly when I compulsively ask for reassurance). I just can’t make my brain stop. I just feel so unsecured. He will mention that one of his friends drove an hour to see him for only 30 minutes. I will then spiral that I am not possibly doing enough and it’s because he’s secretly done with me and he’s longing for a reason to leave and go be with this friend instead. See? Truly irrational. But I cannot stop it. Any tips at all? Maybe I’m at least not alone in this. I often feel literally insane:(

Themes constantly switching. I’ve been suffering with real event ocd the last year and am currently in therapy treating it. it’s nowhere near as bad as it was last year and it’s felt like a nice break. there’s days where it gets bad but i can’t compare it to the stress of last year. However i’ve noticed every time i overcome a theme a new one hits me out of nowhere. i’ve suffered with ocd since i was 9, and ive had multiple themes. i’m in a 2 year relationship with my partner and it’s amazing. she’s probably my second proper relationship due to the fact my first relationship gave me so much fear to get into another one as i was cheated on, and needed a few years to get over that. i kind of guessed that ROCD would creep in at some point as it just felt inevitable. anyways, i know my partner is not cheating on me, she’s beyond loyal, we are so so in love but i think due to that first relationship i had, being cheated on really messed with my head. it’s like my brain is telling me my partner has someone else even though i know in my heart nothings going on, and i trust her with my life. i also think because im in the happiest relationship of my life, anything that would indicate loosing her makes me feel sick and riddled with anxiety. and i know that’s completely normal for everyone. i think the most frustrating thing is, is knowing that my OCD has finally crept into my relationship which is something i never wanted it to do. this is a brand new theme and i have no idea how to treat this. i will speak to my therapist but if anyone has been through this theme and any advice in the meantime i would really appreciate it :).

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)?
