These major events are hard. I was a candidate for a big-deal thing years ago and was horrified but felt like I couldn't say no or tell anyone how horrified I was (I was supposed to just be happy and excited, right? :nailbiting::wtf::speechless:). I don't have any advice on the trip or anything, but are you able to create some sort of phrase for yourself like, "I want to go, but I do not have to go..." and imagine setting it on a little shelf in your mind for later? You can see the doctor, which will give you more information to help you not feel so torn...like hopefully the info will help you feel more sure of going or more sure of not going. But I hear that you are perfectly caught right now and I know that's a yucky feeling.
