I remember that this video caused quite some emotional commotion on Facebook two months ago or so. I guess that it'll be more effective if you can relate to him, as I more or less felt a bit awkward when watching it for the first time. The whole "feel sorry for me" concept isn't really my cup of tea either. (/mood ruiner)
But, yeah, you might as well give it a shot. The song itself is enough to make me feel a bit low.
