Give it some time. Be patient with yourself. If you get too frustrated, you'll just make it harder on yourself. Why? because your frustration will end up being the tool to hold onto your past.

Frustration is kind of like using a glue board to get rid of flies. You're going to end up getting the flies stuck, but they won't be gone, they'll just be temporarily incapacitated. If you just relax and let the flies buzz around, they'll eventually leave and you can go back to whatever it is you were doing.
