I know how you feel, I have lovely boobs at the moment (36DD) but know that they are the first to go!
But also, the fat around my neck and chin goes too, and gives me a better jaw line.
but then, I am fairly flat faced (from a profile pic) and would love a bigger nose! (we never love what we have to we! lol)
my legs are ok at the mo, and quite nice when I am slim, so i try to look at the posistives.
there is always something we want to change, however, our 'task' really, is to make the most of who we are - we are ment to be this way, its God given, and He loves us even on our most ugly feeling fat day with crazy medusa hair (me on a morning), and we should accept and love ourselves.
to chill out I have an exercise that I do, I use it for praying too, but if you are not religious you can skip the praying bit:
sit in a quiet and warm area, breathe deeply, almost like you are sighing for a few mins and drink a hot drink, like tea.
focus on your mid-chest and solar plexus area feeling warm and calm, keep breathing deeply, and either pray if thats your thing (God, please give me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference) or if you dont want to pray, say comforting things to yourself, 'its ok Jonesy, you are normal, just relax a little, love yourself a little more, its ok' something like that.
I know some of you may be reaching for the bucket, but this works for me, its a very private thing, so do it alone without announcing your intention to anyone, just take a few mins for you.
if I am in a busy area I go to the loo, and yes, I have taken tea with me sometimes too
give your self a love love.
