Am i not pretty enough?

Went back to school today....
It was awful. I'll admit that i am a little bit self centered. When i plonk myself down at lunch, i fill the awkward silences and when we speak about something, i admit that a lot of the time i relate it to personal experiences or i chatter on and on cause i am excited.
Today i heard that a lot of them think i am a self obsessed, self centered bitch. So i felt a little self conscious of that and then they all asked me if something was wrong.
I went to drama that afternoon and there's this cute british guy there, in the year above me. He hits on my friend a lot because she's funny, they're cracking jokes all the time, but of course, i have to be the one with morales and respect so i pay attention and then of course theres the fact that i am not funny, really, i cannot crack a joke without stopping half way through it, getting confused and having to start again.
I eventually gave up. This totally hot guy already thinks i am a no nothing loser. "Am i too outspoken, don't i make you laugh?"
Today we live in a society where all teenagers think that being smart is uncool and standing out and voicing your opinions is way too "goodie goodie teachers pet" Like for instance wth my group, they pay me out all the time and say things like "It's gay" and "who cares" or "what for"

Then, the cherry on top of today, dad came home only to talk of how great sister number 3 is going tennis. He loves to watch her. Him and sister number 2 always joke around like they have this inside joke they tell no one about. I have nothing. At my drama theatre comp he sat in the audience and gave me these faces, like, "How much longer!"
I got into the finals and he said he couldn't turn up. Is it because i don't play a sport? "I try as hard as i can"
Maybe it's not enough?

or maybe i should stop talking about myself and talk about the footy score, or maybe Richard Pratt's death, or maybe human issues like poverty in third world countries, would that make everyone happy?
