I don't know what I'm doing in my life anymore

i used to be a person who keeps everything in organized order. i get my work down early, i spend time to myself, i am well aware of my surroundings, i even have my own ten year plan. but now, it all changed, i become reckless and i have no freaking idea what i am doing right now. I'm so exhausted, i want to finish all my homeworks because i set a standards in me, but I don't think i can fulfill it anymore. and my parents changed too, they think that all this sh8ty schoolworks will be a piece of cake, they've been expecting very good remarks in me, I don't think i can anymore. I'm not sure with my life right now, i just wanna lay on my bed but with me lying in bed for weeks, ignoring all the responsibilities i have in me, was no help. i don't know what to do anymore, I'm tired, I don't know how long i could keep going.
