i have depression :(?

at school i was lefted out of social stuff, and ppl think i was trash. ppl never liked me :( i hate my self all the time, I think im helpless. anyways what happened today made me cry. i got my report card, yeah im asian. but i did better than the last report card. because the last report card has Fs and mine got better but it was just Cs. My mom was yelling at me, threathened me, say really mean stuff, compared me to my brother ( who get As ) , and says I need to excersise (im skinny and she's fat wtf), threathened to hurt me when i get in the house, said ( actually gave details) and think im one of those barbie dolls who do makeup (im insecure about my self and i like makeup), she's like all "EMILY YOU NEED TO GO HOME AND DONT WATCH YOUTUBE AND READ ALL DAY AND DO HISTORY" im just one of the ppl at school. i like different things. :( :( :( :'( :'( It gave me so much depression. I dont feel like eating. I try to cut my self with a shaver but failed at it and bled just a bit. I'm so sad :( I'm actually crying right now. I tried to choke myself with a scarf but cant. I hoped I die some day and live in peace. I feel unwanted and the last person on earth.
