him abusing me made me lose my self esteem

You lose a part of yourself when when a man decides he no longer respects you or your well being and hits you. Disrespects you in front of everyone and I mean everyone including his family. I finally got the strength to leave. I told my mom about the last time he hit me I didn't tell her about the other times. I was getting abused at least once a week. I was so scared of him he threatened me in messages and on the phone last night. I have to hide my car when I live in apartments because I'm afraid of what he might do. 
I have zero self esteem, he basically made me change the way I look, didn't want me to wear weave ALWAYS taking control on my life. 
I just need to know how to gain my self esteem back because I no longer have any.
