Brother invades my privacy?

[Talia]

I'm 14 and he's 15 and he's gotta be on my top list of the most annoying people on earth. Ever since I was born he's been bullying me. He has anger issues but denies it. I thought he would get over that whole annoying phase he was going through, but nope, he still acts like a 5 year old. EVERTHING I do he is obsessed with. Everytime we're in the same room and I'll just scratch my arm, he'll copy me, if I cross my arms, he'll copy me, if I cough, he'll copy me.
He thinks just because he's a year older hes better than me. If I'm "in the way", he'll scream at me to move. I can't even talk to anyone when he's around or he'll listen the whole time and make fun of me later. Now that we have to go to the same school I have to deal with it even more, he'll ask a bunch of questions like, "why'd you trip? Or why do you talk like that?". Don't even get me started about my computer, I can't even count how many accounts I've had to change passwords to or delete because of him. Once he hacked into my facebook just to see all of my conversations and the same on yahoo answers, he would just sit there everyday on his computer looking at all of the questions i ever posted and my fb messages. He obsessed with everything I do! He can't even knock on my door. I have a lock on my door yet he found out a way to unlock and barge in in a second. Just now I was about to go to sleep so I turned off my tv and my lights but went on my iPod to text my friend about personal stuff like my crush, so I locked the door like usual and of course I had to hear the dangling sounding my lock being picked, and in comes my brother. He stands there for a whole minute while i sit up in bed screaming at him to get the f*ck out of my room.But no he just stands there and when I get up he goes behind me just to see what's on my iPod and of course he does and now I'm embarassed since he knows who my crush is now and so he runs out and I start to curse under my breath while I hear him laugh.How do I make him stop?

Go to the mattrasses. Fight harsh with kind. Do this for a while and bite your toungue. He does bad, you come back with good. Trust me.

Install a barrel bolt on the inside of your door or talk to your mother or father it is not proper for a 15 year old boy to be invading a young girls privacy even if he is your brother

Punch him as hard as you can in the head. Trust me, it'll make him stop and scared of you.

Just kick his arse....and ask him to behave properly...
