My sister is driving me crazy

I know that this is long but please read if you can help!

My sister has always been very hard on my head and I have lost all my confidence and self esteem. And most of it is because of her! She has Asperger's. She always tries to bring me down and herself up, like telling me all the complements she recieved that day, all the people that have ever told her she was pretty or liked her hair (what the f*ck right?) Our school has this online grade update and every time she checks MY grades and figures out my averages and then she'l tell me if theyre not good enough. Then she reminds me of how good her grades are. Another thing she did just today, her birthday was recent (but not recent enough to still be talking about it) and she got this card from one of her friends. Her friend wrote that she was pretty, intelligent, etc and she brought it up to me and said "look what I just saw on this card Kathy gave me" (obviously she did NOT just see that part, it was hard to miss) And I read it and said "cool that was nice of her but why did you bring it up to me" then she got all upset and said "no reason" and stormed off angrily.

And, when it comes to friends, I am practically not allowed to have any of my own. She constantly flirts with the guys that like me, stands in the middle of my and my friend when one of them comes over and talks to them nonstop. She always has to be there, and I used to not mind (well, I did mind, but I liked to have her there, if that makes sense) but now I just dont want to talk to her anymore! She has slumber parties, I am not invited, she makes it very clear that she doesnt want me with her friends and she does it very hurtfully.

She also makes "jokes" in which she says "It's no wonder you attract guys with glasses mostly, because they're visions so screwed up, they cant see how ugly you are." and she expects me to laugh? That hurt! I am so tired of her reminding me of how much better she is than me! Shes smart, attracts guys, and she is not a mess like me! I am not jealous though; I am hurt.

Please help me.

(edit: also, she is TERRIBLE to my nine-year-old brother. she yells at him and calls him stupid and he is not. he did nothing to deserve any of the crap she gives him. )

evertime she tries to brag, ignore her.
I have low self esteem as well, so we are on somewhat same page.
if you are talking to one of your friends of a guy you like, and she butts in, tell her that you would like her to go and leave them alone because you were talking to them.
dont listen to he bring you down.
and if it will make you feel any better, ill be your friend...

my bro does that same thing to me so do what l did and find something 2-5 that is vary embarasing to her then when she try's to talk carp get on her about them and just like the other person said ill be youre friend (not takeing pitty on you) butt you,the other person ,and me are kinda alike p.s it is hard to ignore thet so get her back,and email me at taazzmaann@(at)yahoo.com if you want to talk some more

tell her strait up liek be liek yo STOP you need to back up outa my busniess leave me be and jsut let me live (not like that btu you no) and liek just be hard doit back to her show her what it feels liek or jsut walk away when she does it shes getting joy out of what shes doing to you and thats not right soo tell her off

why did it change to "driving me crazy"? that is offensive in a way its more serious WAY more serious that a little annoying. who is doing that??

im not sure what to tell you but that is bucause I have the same damn type of sister, just today she told me I have an ugly pimpled face, my hair is gressy and disgusting and I have no sense of style I dont know how to wear make up and I will never get a guy to like me. then when we went mothers day shopping I wanted to get christian book for my mom so I went to barns and noble and she parked and it started to pour so I asked if she could pull up to the store so I could get out with out getting soaking wet, she wanted to make out with her @ss of a boyfriend, well after I asked she just acted like she was going to pull up and then she just drove us home! I didnt even get a present for my mom and then she said "oh well mom dosnt love you as much as she loves me any way so it dosnt matter!" I hate her so much!!! somedays I love her and would die for her 1000 times over and other days I wish I was the one kiling her. I just dont get why she picks at my confidence like this I hate it. I don't know why I told you all this I guess it was just good to b!tch to someone who has the same issue, fun mail me if you get any good replys to your question
