Hey, part time university lecturer here. You're not the only one who discovers that working with ai in your own education is a slippery slope.
I discuss that with my students sometimes and what we find is that there's a question that helps them out of such a situation; why am I here and not back home in bed right now?
Ultimately it's your life, your choices. And just because you made a choice last week you don't like anymore doesn't mean you have to stick to it. We all make mistakes and we all pay for them with some hardship every now and then. But your mistakes also pay you in a currency that is hard to come by: experience. Might not be nice to be at such a point, but it's no reason to despair. We all are here to learn and not all lessons come in a classes-format.
Might be that your realization is already enough to lift you off the floor right now. Might also be it takes something more (why do you sleep in class? How well do you sleep at night? If not enough or not good enough what's keeping you awake?). Sometimes we need support and there's no age at which it becomes inappropriate to ask for help when you need it. I know, students often think 'I'm no kid anymore, I am independent'. Then they grow older by another few years and realize that being independent doesn't mean being alone ๐
