How do I keep myself sane while living with my parents?

So unfortunately, I have to live with my parents for at least 3 more years until i finish my degree and it feels impossible at this point. I'm about to finish my first year of college and I had a breakdown like every 10 days. My parents won't let me do anything that resembles fun and if I still do it despite their reluctance I get taunted and manipulated to the point I feel like a villain.

It's not even like I want to get drunk or stay out till late, I'm judged for simple things like watching movies or going to the mall. It's not even consistent, sometimes they'll let me do whatever and give me extra money and the next I'm scolded for not eating lunch.

What can I do to ensure my mental peace? Please refrain from giving the obvious answers (you know what they are)
