Tampon Anxiety

So I’m at that point where I’m tired of using pads and I’ve tried to switch over to tampons three times but each and every time I’ve tried I get super dizzy and nauseous to the point I almost throw up. I finally got it in this last time but I had to pull it out as soon as I got it in. I want to get over this because at this point I’m starting to get mad with my own body for not being able to do this. Anybody else experience this?
