I feel ya. In a similar situation rnFor me it happened as a result of being sectioned against my will after a very severe suicide attempt. The psych ward I was imprisoned in gave us literally *nothing* to do to occupy our time. The only things I had to look forward to as a temporary respite from my boredom were the meals and snacks... Needless to say, with no means of weighing myself to make sure things hadn't gotten out of hand I ended up putting on a whopping 30 pounds within my 4 week stay there.
That's like my exact same story. Crazy.Used to b/p a ton, was at my lowest weight, had a bad breakup, then started having lots of fast food and alcohol. Then stopped purging but kept binging. Gained 60lbs over the past two years ;-;
