How come i always have to urge to do bowel movement before working or going to class? could it be i have anxiety? how can i stop this, because its honestly annoying. nothing else besides that?

Anxiety or stress certainly could have this effect. You should speak with your doctor about the best option for you. The main choices may be whether to treat the possible underlying problem (e.g. anxiety treatment, e.g. alprazolam, i.e. Xanax® or similar drug) or to try treating the symptom with a GI anti-motility drug (e.g. loperamide, i.e. Imodium®) an hour before work or class. Good luck.
