Do yourself a favor and get out of the house at least once per day... and keep active... meaning exercise... might sound crazy but simply exercising everyday can make a huge difference in how you feel and your motivation.
Thats what I started to do - wake up - nothing to do... fix myself some shitty breakfast and exercise for half an hour or so... Push ups, etc... And of course, the friends that I have try to take me out and free my mind... But again, drinking, gambling, trying to make me temporary forget that I have the problem. Just need a permanent fix for my brains and heart I guess...
