At 5' 6" and 185 pounds in my female body I am completely disgusted with myself. How could I take such horrible care of myself?

This insane sugar addiction is killing me. At the rate I'm going I very well could be 600 pounds in 2-3 years. I see my nurse practitioner that does my psych meds on Tuesday. Debating calling PCP and going to see him. Maybe he'll have some ideas on how to kick this sugar habit. I mean virtually everything I eat has some sugar/sweetener in it because when I'm hungry I don't feel like making something healthy. And that's the convenience foods laying around the house.

I don't know what to do.
