My entire family assaulted me [16M]

I don't know what to do...

20 minutes ago my entire family ganged up on me and assaulted me.

It started when we got into an argument and my mother told me to go see a psychiatrist and called me insane. I was deeply offended and told her maybe she should do the same.

She responded by beating me repeatedly with a broom stick. I hit her back in self defense, but my dad joined in and attacked me too. As did my brother. I held them off, but there are red marks on my body.

I photographed it all, just in case.

I left the house, because I couldn't stand being in that toxic environment..

Should I call Child Protective Services?

What will they do?

Update: I called the police, the kind officer went to where I was hiding and we talked. He understood my situation and let me fill out a witness statement and will speak with my parents. I'm currently filling out the statement, but I don't know where Im going to stay for the night.

Update: so the officer promised me they wouldn't say a word to me and would leave me alone.

I made a bunch of meals and am walking to the library where I will stay the entire day for the whole week until school starts where I can study and relax.

The officer was reaally nice and genuinely wanted to help me. He offered to talk whenever I needed it, even at 2 AM.

He told me he'd take this seriously, so that's cool.
