Didn't become overweight till I was 40 (except for my 2 pregnancies but weight came off pretty fast afterward). I am bi-polar and had trouble getting stabilized with my meds while going through a severe depression (lasted about 2 years) Doc tried many combinations and I finally found one that pulled me out. During my depression I slept most of the time and ate what was around since I didn't want to cook. Hardly went anywhere and didn't get any excersise. That along with side effects of my meds is where I believe I gained all the weight.

Seems like I woke up one day, looked in the mirror and saw a totally different person....fat! Hated the way I looked but it took about another year before I finally started to do something about it.
