Awful Parents.

Hello. I am currently 19 years old, my parents have family link connected to my phone. They set it as me being younger than 13 so I can't remove it. They say they keep it around to teach me "responsibility" but I call bullshit. They've been controlling me like this for too long. Are there any easy ways to bypass family link? I used to be able to do so using viber, as its notifications always bypassed my downtime even if it didn't have any available apps. Now it's gone, I can't seem to recreate it again. Is there any way for me to redo this bug, or any way I can use the internet by bypassing my downtime? Thanks in advance.
