I Was Physically Abused.

My dad always physically abused my mom when I was younger. They are no longer together. Me and my older brother had a huge argument today and he pinned me on the ground, began choking me and when I got up, he kicked the back of my leg. My mom was fighting him to try get him off of me and eventually he stopped. It’s really brought me down, this happened this morning. It’s now 10PM and I’m just feeling disgusted about it. I do want to go to the police but I feel there isn’t enough evidence. This isn’t the first time he’s done this to me. My mom kind of shook it off for the rest of the day and she is still speaking to my brother. Does anyone else have an idea of what I can do? I can’t afford to move out as I’m unemployed (starting college soon) and I don’t speak to my father. Any help would be appreciated.
