I'm really tired of having screen time I paid for very expensive games that I can't even play, my dad using my computer almost everyday drives me crazy. Why I bought a computer for 800€ to not use it freely ?

There are also my parents who tell me why I don't become a developer ? how can i become a developer with fucking sh*tty screen time ?

Sorry if I'm getting mad but I'm really fed up

I just want to have fun I don't want to wait every time
