I'm bipolar and when you're untreated you can put yourself in some really stupid situatuons.  No you don't treat it with food. I was fat until i was 26 and got my shit together. Overeating is just another unhealthy crutch. Losing weight has made me feel so much happier and confident  being fat is an unnecessary burden that i wish people would stop saying is okay. If it were okay they wouldn't have to say it all the time!
