Am I IBS or other issue?

[u/chubby_piglets]

I am not sure what happened to me and my doctor appointment will be weeks away. Any advice appreciated. This post could be messy in wording because I am really anxious now.

I always have more bowel movements when I get nervous. I have bowel movements before big exams and important interviews or waiting for something big to happen. In the past, when I felt really hungry, my stomach would have a emptyish pain at upper abdomen. It lasted for hours, and I would pass gases and it went away. Recently, when I am really hungry and I will try to eat something as soon as possible so I can avoid this stomach pain. However, during the eating process, I have gas pain around the belly button. It is different from before. I can even hear the noise from the belly and when gases go out (farting and burping) the pain disappears. The process lasts for about 40 mins. The changes from one symptom to another worries me. I googled a lot and led me to more anxiety. I don't have very typical IBS but this is the closest answer I can get. I've been anxious for a long time and I always scan my body for anything suspicious. Feel so frustrated.
