My life,my rule

My friend (I won't use her real name) ill call her "Jessica", was once kind of suicidle and she got really sad one night so she found a bunch of pills (she doesent know what they are) and swallowed them. She had really bad stomach pains since then (its been a month, and the stomach pains have been going away slowly) Also, she gets the pains when she eats. Although the pain slowly keeps becoming easier, it doesent seem to be going away. She does not want anyone but me to know, so she doesent want to see a doctor either because that would involve her telling someone. (She especially doesent want her parents to know). Any medical help atau ideas as to what it might be atau what she can do to fix herself?
