Are you happy, well-rounded? (dealing w/ depression/lack of motivation)
edkennedy: I have felt something similar in the last few months, and have been feeling the repercussions since then. Everything around me in my life was wonderful, in fact it was the best it's ever been. Deeply in love, working at a highly paid highly skilled job, enjoying my free time and continuing to improve my living situation. However, I felt a sincere lack of motivation and my results had started to decline.Recently I have gotten back on track. What assisted me in that process was: 
1. Talking about my feelings and listening to the life experience of my partner. This is humbling. You are not alone.
2. Getting back to the gym. This was a huge motivating force, getting your blood pumping makes you feel alive and is the quickest way to get to where you want to be. I also changed my diet (no more coffee, alcohol, junk food). This takes self discipline. 
3. Lastly I remembered to have fun. The most stressful times for me was when I forgot to do the things that made me happy. Celebration is another part of being alive.
