Mental health question? Am I okay mentally?

Recently this past year I have been going through a lot health wise. I’ve never gotten and STD from my boyfriend before, but he was cheating on me and I ended up doing the same with a past fling. I’ve always been very scared of STDs. Well I was taking a lot of medication that had nothing to do with STDs and one of them was progesterone and estrogen because I wasn’t getting periods. After taking the medication I got my period and a week or so later I started getting really nauseous and headaches, and a white tongue but they weren’t all at the same time well I started looking up symptoms on google and immediately after searching through all the causes one of the ones that popped up was HIV and ever since I’ve been thinking about it I’ve literally thought about it so much to the point where I call doctors ask questions about my blood work from when I had surgery in May and if they seen anything wrong I would ask questions but not really saying what it was I went to get all my latest STD checks from every clinic I had went to since January. I even downloaded an app to talk to a doctor. I went and I got tested on Thursday and I’ve literally been worried sick. I don’t even have sex a lot but I still can get it out of my head I go online and look at symptoms all day. I even made a fake number to contact the other guy and see if would tell me if he had recently got tested or if he had an STD, I asked my ex and he said he felt fine nothing unusual. I’ve been so worried I couldn’t eat and because of that I thought it was a symptom. I’ve thought about killing myself. Is there something’s my wrong with me. Every doctor even my doctor that I just got tested from said that nothing seems out of the ordinary and that everything I was saying could be from something that has nothing to do with an STD even another nurse told me to stop looking on google and calm down. I’m going crazy.

UPDATE:

I tested negative for all STDs/STIs

And I of course had a yeast infections and BV
