I've been a victim of domestic abuse, but I don't know how to get out of the situation, what should I do?

Get a friend or family member you trust to intervine and help get you out of the situation so you don't have to solely do it yourself... and they'll encourage you and remind you you're making the right decision by leaving the abuser.

I'm really sorry you're going through such a difficult situation. It's never easy to get yourself out of it, but thankfully we have quite a nice number of people or organisation that could help. If there's a possibility you can get in touch with them, I'd recommend to do so. Also don't keep it a secret. Share it with people you trust that could help or just be there for you emotionally. I really hope you'll find the help you need and win over this situation. Best of luck
