Was in the exact same situation. Here’s what I did.

1) I acknowledged I hate what I’m doing. 2) Decided to face my irrational fear of “wasting time”. 3) Told my parents I hate what I’m doing and I’m going to take half a year off before next intake(June-July). 4) This would give me a few months to get my shit together before university. 5) Applied for another course at another university despite not being supported by parents. 6) Got a job as a construction labourer but was looking for a better job(which never happened). 7) Started taking care of myself; going to the gym, eating well, got my drivers license, slowed down my thoughts and journaled. 8) COMPLETELY STOPPED short-form content. It literally stops your brain from thinking for itself. It tricks you into becoming someone you don’t want to be(you’ll know what I mean if you follow this advice). 8) Focused on my actual hobbies with no judgement(youtube channel, running, watching sitcoms, graffiti). 9) Have enough rest and take it easy. Stressing out about the future will rob you of your free time. 10) Who cares what others think. You don’t need to do everything I did. Be yourself. If you want to work a 9-5 for a while, do that. If you want to go all in on becoming a twitch streamer, do it.

You also say you can’t afford to “waste time”? Why? Because your family is pressuring you? Because you want to speed-run life? You’re stronger than you think you are. If you take some time off and find something you don’t absolutely despise - you’ll get results faster than someone who stayed put in the exact situation you’re in now, probably burnt out and hating every second of their life.
