Disappointment

Suddenly, I feel that i don't want to trust any of my classmate because of their behavior and attitude had make me
felt annoying and disappointed.
I'm very trusted in them but finally they had shown their true color to me.
Before this, i do have a friend who can speak to but this few days she had changed drastically.
Her changes make me felt like I'm just like a jerk, a stupid girl... I'm feel like I'm being used by her while she's really a good listener.
I don't know why my feeling about her suddenly would change to this...
Maybe it's because of some situation...
Before this, we are best friend, we do homework together, we shopping together.
But when we doing our presentation last week, she was not giving too much concentration and just wanna finishing it by not explain much. this may affected our works but she just look like didn't care.
I care my homework, i care my result, i care all the things that i involved but my classmates didn't care it anymore.
Why I've been posting here to see this lousy things happened on me?
I don't like this place and I don't like people who were irresponsible...
I hope next year our assignment will go in personal but not group works...
I honestly wishing that they will 'wake up' from their dream and be more responsible...
I agree that I'm a perfectionist, what I'm doing or will be done must be tidy and good enough else I'll be no one.
Hopefully next time they won't be that lousy anymore. I wish my wish will come true.
Because of varied incident, I can't trust anyone at all as they just like to speak behind my back.
When will this things stopped? When will they realized that they were wrong?
My heart is getting broken but I'm still have to pretend that I'm strong enough to get through this.

Lord, please send me a sign ~
