Help! Binge eating late at night…

{ 18 year old woman } So I eat great during the day, I eat well balanced meals and then I do my nightly routine and take a mirtazapine pill that my doctor prescribed for depression. I’m not hungry at all, but about 45-60 mins after taking that pill I am craving food so strongly and most nights I give into the craving and end up binging on whatever I can put my hands on. I feel SO out of control during the binge like I just can’t stop. I immediately feel regret, shame and disgust in myself after the binge. I want to stop it so badly… every night I think to myself “you have eaten enough today, you are NOT going to eat again tonight…” but these last few weeks I have been binging every night. The thing is, that tablet is supposed to help depression but my depression has been so much worse because of the binges… and I am gaining weight even though I’m trying to LOSE weight because my BMI is in the overweight range and I don’t feel comfortable or confident in my body. I don’t know what to do can any one give me some advice?
