Suggest Treatment For GERD, Stomach Ulcers And Lack Of Appetite

Hi Dr I'm a 23 year old and I was diagnosed with gerd and stomach ulcers this past year. I was put back on adderall to help with my add and now these last week or so I've been getting sick to the point that I can't even eat anything without getting sick. My family is worried that I'm going to end up bulimic again. Is there any way I can get to stop?
