Is my stomach issue caused by anxiety or something else?

Yeah mostly likely anxiety if you don’t feel it during summer, i get a bitch of a headache and back pain when I’m in a stressful environment

I believe it could be anxiety, so that could be why it only happens at school. If it’s get worse at school by not able to go to the bathroom or things like that. If you’re concerned about it I would say try to see the doctor just to make sure.

I personally have had stomach issues caused by anxiety, I have it very severely though so it’s rare for me to not feel anxious all throughout my body but in milder situations it can be shown through stomach issues, severe headaches, feeling like I need to piss all the time, sometimes it’s just your body without the thoughts
