I know it's hard to get over that hump—that's why so many people keep falling back down. But you have to remember that this is just the stage you go through to get to the other side. It will pass. This will all be a memory. Keep your eyes on the prize—your future. Remember the horrors behind you, too. You've been through worse than this. You can do this. If you turn back, you'll only find more horrors, and then have to go through this all over again.
I think it was Churchill who said that when you find yourself going through hell, keep moving.
