Ever since 11th grade started i have been very sad and feel hopeless. I try to stay home as much as i can,i have over 30 sick day already. I always feel sad and it causes me to not want to do my homework. This past week ive been sick so i havent gone to school. I feel better today but my mom said she doesnt care anymore so ive been crying all morning. I try to let my anger out by punching things and try hurting myself only by punching though, i would never cut myself. It feels like i have no one in the world. No one listens to me and i cant talk to anyone. It feels like because people see me as a pretty happy person its hard for me to seek help or tell anyone. i feel like i should just give up on life and quit school or something. I feel like the only thing im good at is not being near anyone. I used to have a social life but now i just sit at home and do nothing. Im almost 17 and almost a senior in high school but idk if i can make it through senior year. Doesnt really matter at this point since im probably going to get held back. Ive never gotten good grades B's and C's mostly with some A's but not i can barely get C's most of my grades are D's and F's. idk how i can tell my parents how i feel. I feel like because im a guy i cant tell anyone. Im not gonna try to kill myself or anything i cant do that to my friend and family but i do know i need help. I feel like im not going to do anything with my life though so whats the point.

i really need some answers and help

oh and sorry for writing so much but thats how i feel and such
