Desperate need of support

My counselor says that I need to, until I can get on my feet, just survive the relationship. He verbally, emotionally and mentally abuses me but not physically. Because I'm technically "safe" the plan was to ride it out until I'm able to leave. I've been trying so hard but today was impossible. I'm 7 months pregnant and have 2 kids. I'm already on antianxiety and antidepressants to help get me by. I have a counselor and it's still not enough. Everyone tells me I have to be strong for the kids; suck it up or I'm a failure as a mom.  I can't stay at my parents so I'm stuck there. I hate the way he treats me...I hate myself. There's no way out of this now. I have no quality of life. I can't let my kids see me break down and sob in pain. I'm garbage to him and it hurts to have to put up with it. I wish I could disappear and this pain to stop but I'm stuck. So what's left for me when almost none of me left?
