What will happen if i wrote this fake note from my school?

i needed money and my parents would not give me unless it was for a trip..i made a note up saying im going to this trip on school and need 30 dollars. they fell for it and gave me it until my mom called the school to asure it and she found out ,, my teacher sent them a note saying there was no trip.....when i go to school will they talk about it with me? or like give me detetions, expelled/susppended.etc. or will they jus say noting and let my parents deal wit it?
