another but still the same case

Fiiiuuuuhhhhhhhh.......
I'm kinda tired of this feeling...
today,the same thing happened again...
One of my classmate. He doesn't realize I'm his classmate.
He knows my close friends who sit behind me is his classmate.
I don't know how to say it.
It's just...... hhhhhhh.......

I used to cry after I told my mom the story like this. But now I don't want to tell my mom anymore because I think it's not important. and I don't wanna cry.
It's useless.....
If they don't want to say hi with me or I'm an invisible for them,it's up to them.
I don't care anymore.....
I just wanna have my day with peace and smile...
My mom said "It's better for us to know less,if someone want us know something,he/she will tell us by themselves,but if he/she doesn't want to tell us,It's ok"
Actually,I agree with my mom's statement.
It's a good principle-I think....

This month is kinda hard to be passed. I feel so much feeling which I don't like it.
Then I feel a little tired because of the exam.
Then,what else??
emmmm....... I feel something wierd bout my friendship which my friend theresia also feel the same....

But in this month,,,,
I have learned a lot of things....
I got new statement from my mom which I will make it as my new priciple..
Then,I have shared a lot of story with my best friend theresia,so now I know the things which can hurt her feeling. So I won't do that.......
