I was remembering how positive affermations work. Tell yourself "I don't want to be fat" and your subconscience with take it as "I am fat" say "I am not fat" and your subconscience will take it as "I am fat" say "I am thin" and your body will take it as "I am thin" Work on it ;-)
This place makes custom swim suits that cover the "curves", and in as large of a size as you need (I bet you can request even larger!). http://www.modest-swimwear.net/index.htm If swimming will get the pounds off, get a swim suite you are comfy in yo start with. I'm getting one next summer I think.
