Finally

So I think I finally have figured out why I can not just sit and relax anymore. When I relax my mind wonders. When that happens, I start to think about all different things. Eventually I end up thinking about Matt and get sad, depressed and so on. This happened tonight. It has been one of the first times I a long time when I just sat for a while and didn't do anything. I have to keep moving, doing something, checking FB, checking my email, so that I have something else to think about. It's why I worry so much at the smallest thing and just think about everything else that could go bad, but proably won't. I'm glad I realized it, but now how to I get over this? How can I be relaxed about happy again?
