Splinters in my fingers

I am at a really stressful period in my life right now, and usually that tends to bring some pretty nasty OCD stuff to the forefront. When I was around 12 or so (also a really intense and stressful period for me) I had this thing where I was super afraid that I had gotten splinters from this little cactus I had in my room and would tear my fingers up with nail clippers and needles looking for them because I was afraid of getting an infection that would lead to getting my hand amputated. I was able to get a hold on it back then and haven’t dealt with that in a while (probably because I don’t keep house plants anymore, I tend to avoid things that might trigger me which is probably a bad thing but that can be analyzed another day). It’s been ten years since then and that obsession came back the other day. I went morel mushroom hunting with my brother and actually had a lot of fun, but I stuck myself on a thorn and started obsessing about splinters again. I was able to keep it at bay for a whole day but the next day I ended up taking tweezers, clippers, and needles to my finger on and off. My external stressors got worse and I had a huge breakdown in the evening where I was digging and digging and digging with the needles. I kept thinking about infection and how I would have to get my hand amputated. It was on my right hand, which is my dominant one, so I kept thinking about how hard life would be without it. I really like writing and I was spiraling about how I’d never be able to do it again. I couldn’t stop digging until I had cried myself into exhaustion. I actually do think I might’ve had a splinter but I don’t think that really matters because I realized there will always be a splinter and I will never dig deep enough to find it. I went back at it the next morning but finally stopped myself when I felt like I got the splinter. But then I started worrying I had another one on my other finger. That was yesterday. I’ve been wearing band aids on my fingers so that I don’t have to look at them because if I look I’m going to start digging again. And I’m afraid if I spiral worse, I am going to cut my finger open fully. I almost did the other night but stopped myself thinking of infection and nerve damage (so I guess the OCD was helpful? lol). I know the bandaids are a crutch but I’m afraid I’m going to hurt myself (not with the intention to hurt myself, just with the intention of getting the splinters out). My brother asked me to go mushroom hunting with him again this morning and I had to say no even though I wanted to. I was too afraid I would get stuck again and the whole cycle would repeat. I’m just really, really frustrated with myself. I haven’t had an issue this bad in almost two years and I feel like I’ve regressed. I feel like I’m 12 again. I’m so mad at myself for digging and I’m so mad at myself for refusing to do something I liked just because I’m scared. I guess I don’t really know where I am going with this post, maybe just venting. If you’ve dealt with this or something similar, let me know how you have been able to get over that fear or to stop yourself from acting on the compulsion to dig. Thanks everyone
