my parents

hello there. this is the story of my parents. My parents have basically RUINED EVERYTHING. i have strict rules and i feel controlled every second of my life. I have no control or rights in my house; i do not have a voice nor a way to stand up for myself. No matter how much i do and achieve, they always expect more and more from me. its irritating and i have no idea what on gods green earth to do. I get panic attacks and i think i have anxiety but my parents do not believe me and refuse to help me even tho they have witnessed me go through these awful things in front of their own eyes. i need help, someone help me please; i have no idea what to do.
