Depression symptom symptoms and conditions

I was given reglan to aid in digestion while I was being treated for chirosis, and had some negative effects from it, cant remember them now but was taken off of it. I still fight small bouts of depression and anxiety. Now I have to wonder why a doctor from a very reputable hospital would prescribe reglan to a patient with a long history of drinking (that alone is a depression symptom) a pill that has suicidal thoughts as a possible side effect of reglan.
