Purgatory

I'm having a tough time figuring out what to write about today, so I'll just give an account of my day.  I woke up still in a bit of a funk this morning, but I was bound and determined to not let it ruin my day.  I took Junior for a walk, and then I went on a fairly long walk myself.  Usually walks are like therapy for me.  Today, not so much.  Every once in a while, I'll walk, and it makes things worse.  My head just starts stressing out about everything and I can't turn it off today.  Man, I was so freaking frustrated.  It's been a while since that happened.  After I back, I snuggled up w/ Junior for a while and decided to watch the Grey's season premiere.  I was still "moody" afterward, so I lit a candle and took a nice, long bath.  That shoulda cured me, right?!  I mean, who wouldn't kill for a day like this?  Dammit!  Nope...just worse...  Anyway, that's about it.  I'm cooking dinner now, but quite honestly, I just want to go to bed.  Hope it's an early one tonight. 
What do you do to bring yourself out of a funk?  I'm def open to suggestions, except "snap out of it" won't work, so don't use that one ; )
