You are doing the right thing in talking to your friends.... talking about your problems always makes them seem a little bit better.
I think everyone has stretch marks at some point... we all - put on weight.. believe me, I am an expert in putting on weight

.... but the little marks do fade....
Have you ever seen the film Shirley Valentine? They are on the boat, about to make love when Shirley Valentine says... "oh my god, he kissed my stretch marks"... he then says.. "but Shirley, they are a beautiful part of you" never a more true word said!
Go out, enjoy the fresh air, trawl the internet for new ideas around your next costume, read books

etc... and you will soon be feeling better in no time.
I think its safe to say... everyone is always here to listen... and play eye spy
