Watched in your sleep

Just caught my mom watching me in my sleep after randomly waking up at three in the morning. She was staring at me aimlessly, and asked if I was sleeping after I woke up with a racing heartbeat.

My parents live in the same house in separate rooms and haven't talked to each other for 10 years straight. They've used me as a messaging tool ever since I was 7--I'm currently 17. Whenever they wanted to express hatred, they'd gossip to me how much they hated each other and used me to tell the other how they feel. I would be yelled at consistently if I ever got the messaging wrong between them. They refuse to take accountability for their own actions and always blame me. They never have listened to me and only used me to "look good" in front of others and pretend everything is fine.

I'm sorry for the poor grammar, I just woke up and terrified after finding this out.

Is it fine for me to leave this hell after college? I can't take this anymore.
