Definitely, I have gone through the “black valley of despair”.
Every friendship travels at sometime through the black valley of despair. This tests every aspect of your affection. You lose the attraction and the magic. Your sense of each other darkens and your presence is sore. If you can come through this time, it can purify with your love, and falsity and need will fall away. It will bring you onto new ground where affection can grow again. – John O’Donohue
