Stuck In A Hole

I don't know what to do anymore. I've been so miserable lately, and it feels like I will never be happy. I've been depressed for so long, I don't know what happiness feels like. I rarely ever feel any positive emotions. My life is just a bag of **** and I hate it. Nothing works to help me get over this. I don't see the point in going on with life, but my husband would miss me so much. I don't want to do that to him.
