My ssdi goes into my own bank account but my wife bullies me into giving her the money each month. If I leave her can I get the money back?

I’m on SSDI. My wife is very controlling and manipulative. She has taken on average 90% of my monthly checks and all of my back pay. If I don’t sent it to her account she yells at me and puts me down and belittles me until I get so depressed that I give it to her just so she will be nice to me again. I want to leave her and move out but I’m afraid to leave because I have nowhere to go, no car and no one will help me in any way. I’m hopeless at this point and I don’t know what to do. I’m afraid if I don’t give her my money or if I apply for any type of housing that she will kick me out and keep all of my possessions. What can I do? Can I get my money back without sending her to jail? We have children together and I’m afraid my child support will take all of my check so I can’t live on my own.
