I need help

What can I do to get my peace of mind back? My mother in law, i think out of jealousy or whatever ensures that she keeps saying shitty things to me and troubling me because of her words. There is no physical harm but there is mental harm. To the world outside they are very good reputable people, but inside the house they mock every single thing that I do. My husband, no matter how many times I have asked to move out to a new place, does nothing. He keeps quiet, and sides with his mother every single time. He fails to protect me in many major situations. I feel threatened, mentally. I cannot do anything, I cannot focus on myself nor Can i do whatever I like because whatever I do is faulty. I just want to live a free life like other normal people do, I cannot handle the taunts and mocks that I get. What could be the possible things that can happen? Also, I have garnered severe anxiety and depression issues because of them and have to take medication to calm down almost every day. I really need help.
