does sadness make a better writer?

Because tonight I am feeling unsatisfied with myself. First off, I ate three pieces of fried chicken, what is that all about? Just because you see a movie based in the south does not mean you need to eat the food from it!
I joined a gym the second week of school, which was about 8 months ago. I have been swimming probably 19 times and gone to a few yoga classes. Nice way to spend the $30 a month 'eh? It's always like this with me and maybe humankind too. Not doing the things that are good for you and continuing with the comfort of what you've always known and will probably always be until you decide you've had enough. Which is what I did once.
But wait! Look what I've done! I'm rocking in school~ so far one B the rest A's! I've moved to a different city (I have yet to explore and am longing to do.) And I've fallen in love with a wonderful man, yes internets it is not wise to make decisions while having a psychological meltdown. So stuck I am not. But needing a routine I do in deed!
Maybe it should start with my diet? Some exercise each day? I know. I'll try on my wedding dress, that should open my eyes to the fatness bulging beneath!
