Hi Steven,
I find that it helps to do something nice for someone else, to get me out of my own head, so to speak. Call up a friend, spend time with a child, go to the gym and find a workout buddy, something that will give you the opportunity to be there for someone else. I know when I'm feeling miserable the last thing I feel like doing is going out or trying to find the energy to spend time with people but it does help.
