Tired af of SB today

Not that is easy living with SB, but today is being harsher. I'm constipated, full of gases and farting like a skunk. I couldn't skip uni classes, and I'm alert all the time to mt bowel movements so I can avoid farting in class. That increases my anxiety a lot, I just want to be home. I didn't even bring my dinner bcs I'm afraid it'll worse the gases, I'm hungry af. Sorry, I just wanted to ramble with people that may understand. Have you ever went through something similar?
