Best friends?

Hii! sorry that I've delayed my updates... A lot of things are happening right now...

And I just wanna share my problems, so that my viewers that read them, won't feel alone =')

First of all, my problems never come alone... It all started with one, accompanied by another and another..

I used to have 3 best friends, but.....
One of them back stabbed me...
One of them always ignored me even when I'm in front of her...I have no idea whether she did it on purpose or not...
The another one.....I feel as if she's using me...

So I don't know what to say next....
My best friend that ignored me....or maybe not. She pretended that I wasn't there even though I'm directly in front of her.. I don't mean that she has to talk to me or give me her attention... but....if only any of you understand what I'm trying to say. A 'hi' is enough for me or a smile... I'm tired of feeling invisible... and at least she won't be the one....
Last night, I re-read my old diary, we fought in 2010, around June or July... she was in a badmood and so was I... and I can't really remember how it started cause I didn't write in detail..
" So, you lose your best friend, and mine was taken by 'shark'! I feel sorry for you, and I think it's better if I became close to you!!"
" You used me! "
That's what she said. Now we're alright though, until today...but..*sigh* I don't know....I'm confused..

My another best friend, it was 31/12/10 - I saved her text till today.. I remembered that I called her 'baruk' which means ape in a rude way or something..then, she got sensitive cause she misunderstood my intentions...I think I asked her whether she wanna join us playing badminton..but, this is her reply...
*Translated*
" Yeah, the message that you sent, at least be polite. What if someone called you so? "

And I remembered that I said that I'm okey with it if people call me such...

" What if people call you an ape? At least the text is proper, then it's okey if you started to joke around calling people apes, but you, you do it all of a sudden. It feels like you're insulting me, I know, that I can't really hang out with you guys because of my parents... what if people call you such? Won't you be mad? hehe! I'm not mad though.."
 But, it's my bad too, I never thought that she would get offended with that word...

Then, It was on 01/08/11 - she texted me again with another cellphone...
" Hi sis, this is me, can you help me?
" It's okey, I have money problem, can you help me? "
" I wanna pay my notes for this exam. My friend want the money on Wed. But I don't have enough money. I need around $** "

So yeah, I scolded her a lil, by said that when she needs me, she's good to me. But yeah, I just lend her my money.. I mean borrowed her..without even telling anyone..especially, my parents.. It's just a few dollars..
But before that, I did messaged one of my best friend for confirmation, and yeah, she told me that this girl has financial problems... her parents...

Until today, she hasn't pay me.. I don't really mind though.. but she promised. That promise is the most important to me...
Financial problems?? Her clothing is wayyyyy fancier and better than mine... I love being simple though, and so does she.. but whenever 4 of us hang out ( which is once in every blue moon -.-), she looks nice and cool and all.... She bought new phone. It was sooo new, that she wanna buy another new one. She wanna buy a laptop for the shop that I used to work when I was waiting for my O level results... I just don't get it!

And when even she wants me to transfer her phone credit, she'll just say " Sis, transfer me some credit "...
I mean, am I a friend or a toy?

And It was around Jan 4th 2011. She told me something really, really unexpected that I can't share here. I can't believe that I'm involved in this kind of thing... She was scared and so was I...I could just give her advice cause there's nothing I can do to help her rather than stressing out... *sigh* At first, she's afraid that I'll turn my back on her.. but I didn't!
I told one of my cousin, who is abroad about it, he did help me to calm down.. He told me to be by her side cause this is the time she needed me most.. and yeah, I didn't turn my back on her or something.. I did try my best to offer her the best..but it turned out, she never listens...

So, I DON'T KNOW WHAT TO DO!!! I always feel like breaking down whenever I thought about this...

Am I so invisible? A puppet? A bad person? A money changer? A freak?
