How can I recover from an abusive relationship?

Distance, Distance and Distance. Both litarely and mentally, learn from the situation and take away the lesson. And then when you're ready to get back out there, think back and be positive.

I guess first you need to distant yourself from this person who is abusing you in this relationship. Second, you need time to feel the feeling that would come with leaving. The third wave is the most important wave. It can be the turning point for the better, a point that would make you continue the cycle of abuse relationships. Hence, it's important you list down what got you into this relationship, what made you stay and enabled the party to abuse you.

You should immediately look for support. Counseling is a good place to start. Tell your friends/family what has happened or has been happening, even if you don't want to tell anyone, even if it's embarrassing or you feel like you will be a bother, tell the people near you. Remind yourself that you're in pain but you're certainly not broken. Even when you're not sure which way is up anymore, you have to know that there is a stronger version of you whom you're growing into. The path may not be clear but you are walking it. Have faith in the person you will become, the you who is has shed the weight of abuse and mistreatment, who has processed through the pain. Be kind and patient with yourself.
