Should I stand up to my mom?

I’m afraid to stand up to my mom & she cannot talk to me about deep things especially if it has anything to do with my dad. she’s making me go to counseling again so I can talk to the lady. Then the lady tells my mom. Then my mom tells the lady to tell me. Then the lady suggests my mom stay & talk & I go. After the lady talks to my mom & wants to see her back but not me my mom stops taking me until she finds a new lady to take me to when there’s a problem. I don’t like the problems that my mom has & I don’t like that she treats me like I’m still 4. I don’t like that she’s always angry at my dad & won’t let me use or keep the new computer I worked 3 years to get. I’ll be having a birthday soon & I would like to fly to see my dad without having to go the police station for my dad to pick me up. it’s getting embarrassing & there’s always some thing bad that happens when my mom drops me off or picks me up. my dog even barks at her. He thinks she’s the stranger who always takes me from him. He doesn’t understand why I don’t get to live with him & he barks at me when I’ve been gone for a long time. I don’t know how to talk to my mom so she stops fighting with dad when I go to visit him or whenever he calls.
