I ruin peoples time

I feel so shitty because as a kid I used to really enjoy rollercoasters and amusement parks. Even the ones that scared me I still went on and found a way to enjoy them. When I got older I developed anxiety issues but was only affected socially. A year ago I went to Disney with my boyfriend expecting to love all the rides like I did as a kid but I found that I was having a mini panic attack before each ride. I was nauseous and felt dizzy. And then in July I went to six flags with my boyfriend and his family, the same thing happened where I got really nervous and panicked almost the whole day. The second I get near a ride I start imaging what would happen if I threw up or got sick on the ride, what would happen if I passed out, if I had a heart attack, or if the ride malfunctioned. I know I’m thinking negatively but it feels so impossible to control and all I’m doing is ruining everyone’s fun.
