Anxiety about pooping? 😂

For some reason the past couple of years I’ve become really anxiety about having a bowel movement in public. I’m in school and working so I ignore the urge to go but by the time I’m home I don’t need to go anymore. I haven’t pooped in 4 days now and it’s starting to get uncomfortable. I have weeks where I’m constipated and then sometimes I’ll have very loose stools. I know it’s stupid but I can’t get over my fear
