My brother gets all the attention from my parents and he knows i hate it....?

ever since i was little ive been shy,and reserved and anti social.but my brother on the other hand is the exact opposite, outgoing,and very social.so this was my last year in elementary and i was like what the hell i deserve the same life as him right? and it went perfect! people loved me! they came up to me at recess and hugged me and followed me EVERYWHERE! even me and my mom were incredibly tight! we did everything together!! but now,that im moving i have become waaaaaaay more depressed than usual(i HAD ocd,and i have a hormonal imbalance witch switches my mood constantly). and now he is taking advantage of that and acting like i used to to get my moms attention and she fell for it.i have no one to talk to, i cant talk to my mom because she says she treats us the same(not true!!),i cant talk to my dad because he works from 6 in the morning to 11 at night,and i cant tell my brother because when i do hes always like"no, im not LOOKING for attention, everyone just loves me, and not you!).i do have a councellor too, but i dont feel comfertable talking about my home life with her because my mom is always in the session with me.i dont know what to do! i used to love my life,but now, i hate it more than ever...please help.
