It will get better.

To me, this is the saving grace of bipolar: what is happening now WILL pass. It's the nature of the illness. If one can stick it out and try to remember that it will pass... sometimes it's easier knowing that. It's almost a mantra to me in my darkest moments: "This will pass. It always does. It has to; it is the nature of the illness." Not that sometimes it doesn't feel like it will never pass...but it will.
