Why does my stomach hurt every time i eat? i've been really stressed out lately, i haven't been eating often and i'm trying to again. any reasons why?

Have an exam: It's good that you are trying to eat since it is necessary for your health. But it sounds like you've been having a hard time in a few ways at least. See a doctor for a full general exam and let them know about all of these things. You may need lab work or imaging to DX well and you might benefit from a referral to a therapist for eating disorders. This will be a good way to get better. Best!
