LGBT: Am I obsessed with running?

Well you do run a lot! LOL But that is OK...the reason why you feel so good is because exercise increases your endorphins. I am the same way, if I don't exercise I get in a mood, and work stresses me out more etc. I understand that you are probably running more after you and your gf split up. It is a way to relieve stress. At least you aren't smoking excessively, drinking or using drugs to relieve the stress. Running is healthy. I would never discourage it. Just make sure you try not to over do it. Or change things up a bit, by doing some other form of exercise. After a while, running does put a lot of pressure on your knees. Just make sure you carb up.
