I don't just get back in the saddle, I decide to race the horse

It's been a crazy crazy...life. I've been struggling. I heard God's voice but now comes the hard part - following through. Both with the relationship situation and as a Christian. And to deal with both, I first keep myself occupied all the time, and then strive to do my best all the time. As a result I am very tired. I just finished working 20 hours which started Friday at noon and ended on Saturday at 4. Before heading home I spent 2.5 hours at the mall searching for shoes for a wedding next weekend. Then I started getting tired and hungry and angry and depressed, and I was like why did I decide to sign up for a half marathon tomorrow. I walked around the mall looking for shoes but also for more stuff to buy that would make me feel better. But I'm too tight-fisted with my money so I walked around long enough that I realized that nothing would really make me feel better and I should just go home before I buy something really stupid in desperation. I'm not really sure where I'm going with this, but I was just in a bad place again tonight but at some point I realized hey, I really don't care anymore again and now i'm back sitting in my sports bra and gym shorts (this outfit discovery - new favorite perk of living alone), listening to my music (which is obviously perfect), eating spaghetti with salsa and coconut milk...I'm ready to take on the world with God again.
