Overthinking Tampon Use: Could it be TSS?

Hey, I just have a quick question. first, I'd like to say that I have hypochondria, which make me overthink anything that could be medically wrong with me. think of it like ocd, but only in your brain. it doesn't effect anything other than my brain worries to the point if insanity. and I'm like 99% positive nothings really wrong, I would just like some opinions This may be a but stupid, but my brain overthinks my overthinking. Anyway, I'm having the symptoms I've had for the past 5 months, but all of a sudden I started to think something else is wrong and I can't stop worrying about it. So here it goes, I was on my period last week, it ended on the 12th, and I use tampons. So now my brain is overthinking the fact that I could have tss. I've used tampons for almost 2 years now and I've worried about it before, but it's never been anything serious. I don't think its anything serious now either, since I was experiencing ever single symptoms I'm having now for the past 5 months. I've felt everything I'm feeling now for months, but I can't help over obsessing over things that probably aren't true also I know that tss only effects about 20 to 30 percent of menstruating people, so I know it's not super likely. and I never kept a tampon in for .ore than 4 or 5 hours My symptoms are throwing up, nausea, headaches and some dizziness. But like I said, I've been feeling these things previous to now. I also haven't been able to keep as much water down, which would explain the headaches and dizziness. And the throwing up and nausea are obviously things we've been trying to figure out for a while. Anyway, if you could possibly just give me any support on the matter, that would be great. like I said, if anyone has anything they could share that could help ease my mind, it would be much appreciated!
