That's not stress. That's just life, it sucks.
Don't go and 'hurt yourself' over it and be all emo.
Life changes, ups and downs. Blah, blah, blah.
You think your fat? Exercise. No ones perfect.
Be happy with who you are, or do something to change so you can like yourself.
Things change in life constantly, don't get so upset about it.
Make the best out of the worst situations, because you can't change them. And it's dumb to let them bring you down.
