I watched "it's a wonderful life" with my family and it reminded me of how repressed I am

I actually really liked it while it wasn't comfortable to watch I still liked it. But the problem was I can't open up like that around my parents or little sister because she's a hideous brat and my dad just want me to submit to his every whim. And my mom's massive bloated ego won't let anybody criticize her. Fuck these people. I gotta get out of here. I wish I could hold the passion for change in my heart. But instead I just repress, give up, lose the energy I'm gonna learn like Charles crumb.
