so embarrassed...

My professors are upset with me. I have had 3 UTI's this semester and made several trips to the bathroom, my blood sugar is no longer under control(it keeps dropping) and everyone is mad at me. I feel utterly depressed to be honest. My doctors(endocrinologist and ob-gyn) are also mad at me. The last antibiotic made me have 12 rounds of diarrhea and the professor told me I was making too many trips to the bathroom(the alternative was pooping myself or wearing a depend) I was there and trying my best. I have class 4 days a week, work 4-5 days a week, and my husband has been severely ill.

My grades are going to be dinged for all my bathroom trips and when I go to the doctor I get a long angry lecture about going to the bathroom when I need to go....The professors talk for 2-4 hours without breaks. The other classmates outvote me on taking bathroom breaks every single time. We are not allowed to eat in class, nor drink, nor get up to go to the bathroom without permission. One professor was mad at me for going but my period started and it had been 3.5 hours since the last break......when I am at home my husband gets angry at me if I tell him I need to go to the bathroom and will argue with me about it "you said you were going to study we've been studying for 2 hours and now you are trying to just get out of studying" ....I unfortunately need to go every 3 hours or so and I need to eat a snack once every three hours and a meal every 6-8 hours. Should I get a doctor's note about this? At work I can go when I need to but often don't get a chance to eat and my blood sugar plummets. I am super embarrassed but occasionally I've had some urine dribble out but this is only after not going for 6-8 hours and asking repeatedly to go......I guess I need to talk to the doctor about this.....
