I need a cover up for my coverup

I used to have the kind of shape that made men drool and women envious...and then there were kids. After my first child I went from a size 7 to a size 12; with the second I went from a size 12 to a size 16. Two kids later I am a size 24. I have turned in my pretty panties for granny panties; and cute little shirts for baby doll shirts (I'm 32 y'all). I have always had a distorted body image, when I was small I thought I was fat, when I started to get fat I thought I was sexy. I have always carried my weight well and been curvacious so my weight gain looked o.k. for a long time. It was like I became obese overnight. I realized how much weight I had gained when my cousin and I went on a trip and I attempted to wear a bathing suit. I hadn't worn a bathing suit in years; maybe if I had things would have never gotten this out of hand. I put on my bathing suit and sashayed to the mirror and stood there frozen in horror after I caught a glimpse of my body. I stood there speechless looking at my reflection for the longest time. When I came out of my daze I looked at my cousin and said "damn,I need a cover up for my cover up". Things have gone downhill ever since. now I am ready to loose the weight and don't know where to start.
