Being emotionally, verbally & mentally abused.

Just wondering what advice you all can give me. Been in a marriage that is making me cut myself. I had my son 6 months ago & am barely eating. Maybe once or not at all. I am extremely depressed & I just want to feel loved again. I am constantly being accused of something, being put down, harsh things being said to me, the past being brought up & used against me, everything is my fault, no matter what I do it's never right. Please give me advice!
