<human>: Summarize the given text in a few sentences.

Hi everybody! I'm 28/5'5/200 lbs, which is major victory because six months ago I weighed 250.  I lost the weight mostly through calorie counting, and trying to up my activity slightly (park farther from store entrances, take the stairs, that sort of thing.)  I have 60 lbs to go to hit my goal weight.  
My problem is this:  I've had weight issues ever since puberty, and while I try to keep to a healthy lifestyle, rather than diet mentality, I am very, very, much in the habit of trying to keep myself from overeating.  However, I just went back on two medications that have weight loss as a side effect, one of which kills my appetite COMPLETELY.  
I know, given my fairly low exercise lifestyle, I should eat around 1200 calories a day, minimum.  But because most of my overeating was emotional/boredom related, I've spent over a decade trying to train myself to only eat if I'm really hungry.  I'm finding it very difficult to eat more than 600-700 calories a day now.  
Does anyone have any tips on restructuring my mindset?  Breaking the "Eating when you aren't hungry isn't healthy, it's very very bad!" mentality is proving really difficult, and I don't want to compromise my health.
<bot>: Trained myself that eating when I'm not hungry is very bad; now on meds that kill my appetite; don't wan't to mess up my health/attitude towards food and weight by eating way too little.
