Why the fuck won't he leave me alone?

[Shana]

There's this annoying fat guy in my classes and he keeps on talking about me right in front of me. I'm the shy . quiet , mysterious type and I'm a loner...he found my twitter account and is an immature twat about it. he uses the fact fact that I have one against me and apparently having one doesn't suit my personality. Its kind of trivial but he gets on my nerves , is he trying to provoke me?
he's also read everything on my Twitter including private things (I use a fake name on my username) and he also uses that against me and he thinks he "knows" me , his friends which are bitchy girls also join in and make fun of me
They all RT'D something I tweeted months ago
Sorry if this is hard to understand , I rushed this cause I'm at school
I didn't mean to call him fat , its cause I'm angry. He brings everything up , he's a bigheaded wanker!
I am far from attention seeking , I'm too introverted to be that and I hate getting any attention , that's why I hate it when people talk about me!
I keep myself to myself. I get bullied in school and Twitter helps me express myself and I've made friends. The last thing I want is for people in school to find me
I'm trying to say that he isn't visually appealing so you lot don''t assume that I "fancy" him. He calls himself fat anyway!
I want to get away from school people because it reminds me of my friends death( she committed suicide because she lost her baby , her bf was unsupportive and abusive to her and me...)

I'm looking for a solution and advice not attention!
I don't like being reminded of school when I'm at home
Why would I keep my acc private if I wanted followers?
He found my twitter account by hacking onto my blog , he's trying to provoke me caue I'm quiet and closed.
My friend wasn't slutty , she was gullible.
He is my friends distant cousin! She was an "emo" girl and he uses the fact that I was friends with her against me , he used to call her a freak cause of her differences.I'm not blaming him

If you don't want people reading and reTweeting, stay off of Twitter.
You sound like an idiot:
"I'm the shy . quiet , mysterious type and I'm a loner"
Obviously not, you're whiny and histrionic, just like every other teenager.
If someone being overweight is that big a turnoff for you, you have way bigger problems.
Get over yourself, precious.

EDIT:
And yet you have a Twitter account and here you are on Y!A, looking for attention.
You most definitely "meant" to call him fat; it was the first adjective you used to describe him.
Stop acting like a baby and grow up.

EDIT 2:
Your "question" is all over the place. Now you're upset because your slutty teenaged friend killed herself because she didn't have a condom and that's why you hate this guy?
You are projecting, fix your own problems instead of blaming this kid who only accessed what YOU put out there in social media.
You are not clever, you're not deep or mysterious, you are simply looking for attention. If you really didn't want anyone to find you, you would have kept your Twitter account private.
Go talk to your parents, we can't "help" you.

Unfortunately, that is the risk you take when you broadcast your personal information to Joe Public.
However if you're using a fake name, then how does he know it's your account? If it was linked to your blog and available for anyone to see, then he wasn't out of his rights to read what was posted in a public domain.
But in the meantime, try to let the immature teasing go over your head. He's obviously very unhappy with himself, because he feels the need to victimize you in order to make himself look cool. He's probably very insecure and desperate to be liked. If he's trying to provoke you, don't let him. Keep your cool and he'll realise he's not getting to you. If it gets much worse, then tell your teacher.
In the meantime, it might be an idea to delete your blog and your Twitter account, if you want your privacy. But if it's a stress release for you, and you don't want to lose the friends you've made on Twitter, at least create a brand new account with no way it can be traced back to you.
