Hayward said this;
Oh, you don't need to be sorry. Seriously. It is not your fault- you have done nothing to deserve these sad feelings, so acknowledge them, they are real and you are being heard and I am sorry that you are feeling so sad.
I have been where you are, and this I know: these feelings will pass. It doesn't mean they won't come back, but right now just get through them, to the other side. Maybe it means posting more, or talking to a friend, or taking a walk or just simply going to sleep to wait it out. It will subside I promise. Well, maybe I shouldn't promise, but I think I can say that time will help.
I have to agree with him (her?). It's terrible to be in the midst of the darkness and pain but I think it's safe to say that all of us here care because we've all been there too many times and we know how it feels.

Take Hayward's advice......
