How to punish myself?

I know this is a stupid question that's about to be reported, and I've asked a similar question, but I need to punish myself for 2 reasons seperate. 1: Because I just had an answer reported yesterday AND today, and 2: Because I failed this semester of Algebra 1. I had a C in quarter 1, an F in quarter 2, and a D in general. I did study some, but I still need severe [umishment because I hope it motivates me to do well in school and to stop making so many violations. I was thinking of studying, church, and family time and not letting myself enjoy anything else except Sundays once school gets back in. For now, I'll punish myself by making myself copy the Y!A community guidlines and terms of service. Does this sound too harsh? What would be a better punishment, if you can think of any? Thank you.
