Does anyone have ocd revolving around the fear of puking? What do you do to deal with it?

This has recently developed into something much bigger than it originally was. When this past winter season started, i noticed more people were getting the stomach bug than usual. I was fine at first, until I was noticing almost one person in every class was saying they recently had it. I researched about it, and I found what I was looking for unfortunately. Norovirus cases were surging across the U.S because of a new strain of NoV that recently had been spreading. This immediately altered my way of thinking. Everywhere I went, I would be overly cautious of what’s around me and whose around me. The first obsessive compulsive problem I had was that I couldn’t eat at lunch anymore unless I washed my hands. One time, I didn’t have an option to wash my hands, so I didn’t eat lunch. That’s when I knew it was interfering with my daily life, and it was becoming a serious issue. There was another time where some guy threw up near me in the hallway trash can. My mind was spiraling. all. day. long. It felt like it was consuming me alive. Not a minute would go by where I wouldn’t think about it, and the high possibility of me catching this virus. There’s been so many other scenarios where I feel myself losing it. I’m not the best of explaining in detail how my mind feels when it spirals, but the best thing I could say is that I could feel myself slowly losing my mind. It takes over my life. I HAVE to act on my compulsive acts, if not, i’ll have these obsessive thoughts until it consumes me whole. I’ve had nervous breakdowns, panic attacks, anxiety attacks, insomnia, and it almost feels like it’s causing me to have an eating disorder. Most recently, I went to use the bathroom and saw what looked like puke on the toilet seat. I was already using it, so I just finished my buisness and rushed out there asap. I figured, if I fasted for two days, what’s there to puke if I do catch NoV? So, I did. I missed school because on the second day of fasting, I became very dehydrated. I was weak, and couldn’t move. I realized what this all rooted back to. That’s when I knew I needed help.

I have HOCD and ROCD and it makes me wanna puke all day I live with my husband

This is my first time posting - I have a fear of throw up and I’ve been told it is cause from my OCD (repetitive thoughts) which makes sense because if someone gets sick it replays over and over again and I can’t get it out of my head. It’s gotten a lot worse in the past maybe two years. I’m always on edge that someone is going to get sick around me. I’ve heard the “best or most common” way to help with this is exposure therapy and OBVIOUSLY I don’t want to do that. Anyone have any tips or anything for this (or maybe have done the exposure therapy)?
