Replying to Could use some help

well im having troubles getting motivated to do homework, and its causing my grades to fall pretty bad. my mom emailed most of my teachers the other day to check where i was for grades and shit and i have 3 C's, a B+ and most likely an A or A+

the c's are in calculus, physics, and ap gov... pretty much the three hard courses (b+ is english, a+ is photography... i won most artistic for senior superlatives, art is the only thing that really comes natural to me /claim)

not that bad... but then all those teachers that said i had c's also mentioned i had homework assignments missing. of course i do, i rarely do it. i get home every day and just go on the computer and say im doing homework but then i just sit there and do nothing, talk to people, watch movies, play jibbin, make edits of jibbin, photo stuff. not only am i doing nothing, but im staying up until atleast 1AM... thus causing me to be pretty much dead in the morning and half of my classes. ive got easy classes in the morning that dont really have homework or the teachers are laid back and dont care if youre finishing it up during class so i do that, then ive got a study hall before lunch 4 days a week and i get some homework done then. (this is gonna be a long rant im realizing) she has pretty much taken skiing away from me, which is the one thing that i really need right now to relieve stress and forget about everything. supposedly i agreed that if i didnt make honor the last quarter of my junior year, i wouldnt be getting another season pass this year. well i know i wouldnt have agreed to that since i hadnt made honor roll yet my junior year... 2.89 pissed me off for so long.

my mom gets these emails and confronts me with this whole spiel about whether or not i want to go to college and stuff because i dont care about anything anymore, that i cant have these c's and that i obviously am not doing homework while im on the computer. she asks if something is wrong at school or anything and i basically wanted to scream fuck off at her, that she never even had to take calculus, she only applied to one college to my four that all have a different application, essay, portfolio requirement and all that. that my brother was able to get into college without making honor roll once through high school and he is doing great.

she even admits that she is blackmailing me with skiing and that i cant ski if that comes before school... what the fuuck?! i just want to show her the work that i have to do and see if she could do it and get at least a c in all the classes. and its not like they will stay as c's for long, i missed three days in math which caused me to miss 3 assignments, i also missed 2 days of physics, and two tests in gov that i wasnt prepared for after i got back and got shitty grades on them.

blahh, no sparknotes. only the people who actually read it will be able to give help if there is anything that can be done to help
