Always out done

i've been feeling really left out and forgotten lately by my mom, my brother's always gotten bad grades he just could never focus and we found out he had adhd and add so we put him on medicine and now he's doing amazing and getting strait a's which is awesome i'm happy for him truly but every time he brings home an a my mom is just like " OH MY GOSH!!!! SEAN THATS AMAZING!!!!!! IM SO PROUD OF YOU! You want a surprise here! heres this this and this! " and then theres me: "he mom i got 2 of my pieces on display and these are just the first 2 projects! and i have a b+ in math just 1% shy of an a(unheard of in math for me) and i got a 97 on my spanish test!(freaking mind blowing this is spanish 2 and i dont know anything) i even got on the honor role! " "ya thats nice, good job" half the time she's not even looking at me its like she didnt even hear me and she just says it like she's completely distracted and doesnt care at all, this always used to happen with my sister even though she got horrible grades and got in trouble and my were strait a's i feel like i'm always running but this shadow always looms over me its like i can never be good enough no matter what i dont even read my poems to her anymore she just seems uninterested and always ask what the pple in poetry club think about my depressing poems THEY'RE NOT ALL DEPRESSING! i've written some happy and love ones too. i use them to vent without them i could never express what i feel openly and it hurts that she said that so i havent been reading them i've just been distancing myself, lately i'm always angry with my brother and mom it like as soon as i get home theres just so much anger i havent told her how i felt i was going to but in a fit or rage i told sean that a hated coming home because of them and he told my mom and then she got mad and played it like she was the victim! which made me even more mad! she constantly baby's him never scolding or getting onto him so im always the bad guy i do everything for him seriously i cook, clean his room, pick out his clothes, basically do his homework,do his chores, everything and i mean i can understand that she's tired when she gets home from work but cant i have a break too?? she gets on to me for the tone i use with him and getting onto him but at least i have one! why dont you freaking keep you kid in check!? i feel like i'm just the maid living here sometimes, i mean i would never wish i wasnt here or anything but a little back up and even a little bit of this stuff lifted from my shoulders would be nice *sigh* i guess i'll stop ranting now sorry
