Hey Tara,
before I begin my short reply let me you
I can't say I've been there because fortunately I haven't, but one of my closest friends called such a place home for a long while and I found that the best way to get out of it is to go to all lengths to make yourself busy and surround yourself with people you love and things/activities that you find pleasure in in order to distract you from whatever is getting you down. In the end life is always worth living and if you feel like you're at the bottom of a pit, there's nowhere to go but up since you already know there's nothing below and to the sides there's nothing worth staying for. You never know wat tomorrow brings and right now, it seems like there's little it could that would make you feel worse.
till you turn blue
