Wow!!! TG, you are such a star.
On the swimsuit thing--pick your times, and go to the pool when it's full of old bids and new moms. You'll find that you're the thinnest person there by far, as well as the fittest (which is always cheering!), which will give you chance to get used to wearing so little in public. . . And after the initial alarm's worn off, you'll be able to go anytime! When, incidentaly, you'll find that you're still in the thinner and fitter category, if our local pool's anything to go by!
