I've f★cked up my life! Is it even possible to change?

I've f★cked up my life! Is it even possible to change? I'm 25F, turning 26 this years! I realized I spent the past 7-9 years, locked inside my bedroom scrolling the internet! I wanted to die, still do, but couldn't find a way too. I feel so guilty, my parents sent me to university to study but I hated my CS degree and I didn't go to classes. I feel so so guilty about everything and so behind. My parents are getting older, they want to live too but Im such an overgrown baby. I feel terrible. I want to change, really really want to. But I don't know how. I have no friends, no boyfriend, no hobbies, no job, no college education, no fun and no money.
