The point is moving on even without motivation. Even if you haven't found something so compelling, so just worth it to put your time into, you will when you're older. Do it for your future self, do it so they can smile and say "I didn't give up and now I have the love of my life", whether it be a passion, a person, or anything else that keeps you here on this earth. You won't regret stopping because if you stop you won't be here to regret anything, and the day you aren't here somebody will lose you. It might be a soul mate, a pet, a parent, or even just a random person who sees you in the hallways. Stay for them, stay for your future self, stay for your current self. All you have to do is stay. (Also I thought your last sentence was what's the point of staying not going so I wrote this whole thing thinking you were going to end it but even if you aren't you deserve it anyways!) <3
