hates school

i  hate school. i cannot stand my school so i skip it almost every day. luckily, i am a smart person and i'm in all of the advanced classes and don't have reputation as a rebel. only the people who really know me know about my strange feelings. my parents don't care  - they don't even mention it if i don't go to school. what i end up doing is sleeping all day and then staying up all night talking to my imagination. i get behind in my work and when i try to go back to school i get a bunch of crap from my teacher and all of my friends juat laugh. i just get so depressed when i think about it. i have given up on trying to go back and now am considering dropping out altogether, but i really don;t want to do that because i realize it would ruin my life. i don't want to go back at all but i also don't want to ruin my life. i am so confused and i have really tried to go back and just can't take it. what should i do? :)
