So confused and scared !

Ok. So I did not put my whole name on my profile because I am afraid of the repercussions of my in-laws! I have recently realized that I am in a verbally abusive marriage. I have been with my SO for 23 years. I have been brainwashed so to speak. It wasn’t till recently that I realized this and woke up. It took my daughter coming to me and saying that she was afraid of her own dad that I took a hard look and said wtf! Wtf have I done! She is 12 years old! I did not realize how trained I was! He gets mad and I jump to fix it or apologize for whatever the problem is. I’m tired of being a trained monkey. The dogs are treated better then me. I discovered that he is what as referred to as a covert narcissistic sociopath. His mom is one to. I’m afraid to leave. Before I knew his mom was one to I confided in her a bit and she tells me to stay! She “believes in the vows!” But she escaped a marriage just like mine! She admits that he is verbally abusive! She tells me to stick it out! Mind you he has told me that he has had dreams of killing myself and our daughter! He is a disabled veteran with a head injury!! I know I have to get away! But we are in this stupid lockdown and I am a severe asthmatic and I have a weakened immune system! I’m terrified of him! I tried to get away once all ready and it blew up in my face!!! I’m so scared and I have no body I trust! Anyone have advice? Please be nice! I can’t take much more!
