This may or may not help any, but try to look at every day as a new day. A way to start over. Granted doing so isn't that easy. It took me awhile to adapt.
Anyway, a good way to escape from reality, is to close your eyes and pretend your somewhere else. In a forest, a beach, wherever your imagination takes you. Feed into it and picture it. Focus on your breathing. Imagine objects and people if you wish. Eventually you'll start to calm down and it should clear your mind. For how long? Couldn't tell you, but then you can do it all over again.
I hope this helps, even just a little bit
