Why are young adults pressured to figure out what job they’ll do for the rest of their lives?

Hey, I’m 19f and have had a lot of pressures from parents and outsiders to figure out what I’ll be doing for the rest of my life. I’m enrolled into university and I am grateful but I am dreading it as I’m burnt out from having to deal with childhood trauma and having to work while I was in HS. I’m also terrified of debt. It was always amazes me because on one end - everyone says you have plenty of time to decide and the next I’m pressured into uni or else i’ll have to deal with the consequences. I can’t just move away as I don’t have the savings for that yet.
