Every single day at school during my 3rd period I get very nervous for my 4th period and my stomach starts to ache badly, it's like there are gases in my stomach, and I get very gassy. I think I get nervous because I start thinking about this girl I'm very intimidated by, but I wouldn't think that it would make me this anxious. And then in my 3rd period I have to go to the washroom to do number two, and it's usually diarrhea. And that happens every single day in 3rd period. No matter what I do to try to calm myself nothing seems to work, I tried breathing patterns but I just get nervous again. Maybe it's because I eat lunch before 3rd period, but it's every single day that my stomach is aching. Is it normal to feel this way, I don’t know if I should do something about it
