Hello, i am a 16 year old female who has had persistent headaches, extreme nausea, back pain, cramping, bloatedness, overall abdominal pain, feeling like i have to go to the bathroom even if i already have, etc. this has gone on for some time and my anxiety disorder has made it worse, i got a stomach xray this year and they didn't find anything but it is causing me pain and stress, what should i do?
