still feel scared even when she's not around

Is it weird that even after moving out into the college dorms and having more freedom away from my mother I still feel like she's watching my every move? I feel like she still has control over me even if she's not even here. Every time my roommate opens the door I still tense up. I feel on edge when there's footsteps outside the door. I feel like I still have to do certain little things or else I'm scared my mom will get mad even though it shouldn't even matter if she's not around me. Is this normal?

I think it's probably normal for a survivor of an abusive relationship, but it's not normal for someone hasn't been abused.
