anxiety issues

this is the second day in a row when i have to go home because of anxiety induced stomachache. its getting really annoying. im not even sure whats causing the anxiety, theres nothing in school that im afraid of or anything. i’ve always been anxious but it’s getting out of hand and idk what to do. i have to go to school and i don’t want to feel like shit all the time. maybe i should just see a therapist or something.
