Demotivated

I finally have my head back on straight from yesterdays ordeal. I had some thinking time, some talks too, and I noticed something. Just recently, things were getting crazy, with my physical health low, emotionally upset, and work constantly piling up, I felt like I was about to lose it. But then, I found motivation. It helped me get through the hell storm. Once it was over, the motivation was still there, and I felt happy once again. I had the energy once again to pursue my hobbies, picked up a new song on my guitar, began running and lifting again, and took care of myself some more. But all good things apparently come to an end...I had some more talks with some friends, and now I am more confused than ever. I do not know what to do now and its coming to the point where I am beginning to lose that motivation that saved me. It stopped the dust from collecting on my guitar. It made me switch from the 20 pounds to the 40 pounds. It made me run along the Hudson River many nights. Every time I try to work more with this motivation, it seems that everything I do goes wrong. Nothing is going right! And my friends sure are not helping with it. I don't think I can keep this motivation anymore. As extremely cliche I think this sound and as much as I hate hear this phrase, it made me better, but now, I lost the motivation to keep the motivation. I don't know what to do now...
