Need help calming down from trigger

I'm keeping it light hearted but I really desperately need some help. Just to preface this is very tmi. I thought it was just gonna be a quick bathroom stuff. No! That would be silly of course, so number two decided to screw things up ROYALLY. And please bear with me because I am coping with humour 😭😭. So I went, but sometimes, tmi, I struggle to.... Get it all. Out. If you know what I mean. Which is pretty awful to the point I'm like genuinely praying. Because you can't clean up properly if you're not done. So I'm in the bathroom, trying, for over half an hour. And I finally give up pretty much and try and clean up. Oh no, that was a huge mistake. But what else could I do? It was so messy that I wanted to just get in the shower and be done with it. Onto the things I'm worrying about I guess. On the tp (tmi, I'm WARNING 😭😭) it was.... Messy, and there were very loose specks on the tp. Which is an issue, because I used wet wipes which needs to be binned and not flushed, so I have to carry the tp-wipe combo over to the bin, which means carrying it over where my legs are, and thus where my clothes also are. I hate it. I'm now paranoid specks fell into my underwear! Great! Love it. I'm also paranoid specks or just #2 in general went on my hand. And, believe me, with the state of things, it was POSSIBLE. So when I'm finally done and wash my hands, of course that isn't going to feel like enough. I have really short nails, so short they're painful, and I'm always terrified stuff gets under them. So, I use a nail brush while washing my hands. I also filed them down (which HURT) because I'm convinced that could get rid of anything underneath them. But it still doesn't feel enough. Because I have loose skin and hangnails around my nails, and I'm paranoid as well that stuff gets under dry skin. Not to mention my hands are so dry from washing that they're cracked and flaky and they peel, so I am worried that #2 or dirt gets under the flakes of skin. I know it sounds stupid, but I am so scared. Usually it feels irrational but it was such a state that I'm convinced there must be a speck of it on me somewhere. On my hands. And I'm terrified. I know I need to accept uncertainty but I'm struggling right now.

This fear keeps coming back and it’s to the point I cry and what to panic. I no longer talk to the man simply because I wanted to move on and find something meaningful to have with someone (relationship wise). I still keep fearing I need to go get my blood checked. Thoughts like “what if I have it and don’t know it and give to someone?” “What if that urine test I took months ago didn’t work” I got tested for stds but it came back negative. They took a urine test but google says you have to have your blood drawn!! I’m so scared. My mind tells me “you have HIV” and then a sense of peace comes and scares me even more!!!

I was trying to put a bag of screwdrivers away and one of them got caught into my finger and left a small puncture. I was bleeding a bit but I applied pressure, the bleeding stopped, and then I put a bandage on. Then I got worries about tetanus and I saw that this is a pretty fatal infection that could possibly happen and it makes me want to visit an urgent care tomorrow for a tetanus shot. It's only a small little puncture wound, but I've took about 5 minutes to wash it with soap and water and then put a bandage on it. Should I still be worried about this?
