My first note.

Hi, everybody!
I just wanna tell you something about myself.
I know, nobody cares, but I'd like to write anything something at least.
All my life I've tried to be the first at everything everywhere: at home, at school, on some competitions.
But recently anything's things have changed.
I feel better when I'm sitting at home and doing absolutely nothing.
It's awful, I feel like I've lost the taste of for life and I just can't find it.

Now I've decided to focus on learning English.
I'd be grateful for a critique of this note and for your help.
Thanks in advance.
