Considering fleeing my house.

So I’m 15, 16 in october. My parents are genuinely making me consider running from home. I am currently homeschooled, so I have no real face to face connection to others. And they’re moving to stop me from being on Discord and eventually all of online. Discord is my last social fortress in my life. I’ve been emotionally neglected, including when I was in 7th grade when my mental health was the lowest it ever was, and I told them I was depressed and they said “fox your grades instead” for example. Before you ask “well what about CPS” They blindly agree with parents 99% of the time. That’s a no. One thing making me hesitate is my Dog, she’s the only one who truly loves me, who treats me decently. If I leave she might be hurt by this. She’ll never know she wasn’t the problem. Some advice please.
