If you feel stuck and you just do not know what to do or where to go, there are solutions. Every person in an abusive relationship feels stuck at one point. When you have friends or family that are close to you, I would start there first. Most people will be happy that you are leaving an abusive situation and welcome you with open arms.
Tell your friends and family the ugly truth and 99.9% (if not 100%) of the time you will get multiple offerings to help you get out and even get a place to live. Now is the time to be honest with yourself and others.
If you are not close with anyone then there are numerous places that provide support in various ways.
Below are some good resources if you need help right now.
