Frustration!!

What is my biggest frustration right now? Why is it bothering me right now? How is it affecting me at the moment? Frustration is the hardest thing to deal with because it could really hurt or you can be really mad. Everyone has a frustration that bothers them at a point in there life. There's never just one frustration ever in your life. There always has to be one huge tradegy that happens that really affects you.
My biggest frustration is how people keep dropping out of my life as i get closer to graduating or starting something brand new in my life someone leaves drops me like a piece of trash or someone passes in my life. I graduated June 8, 2007, after graduating Cantwell Sacred Heart of Mary High School most of my friends dropped me like a piece of trash. Things happen for a reason and people change and we all grow at different times so i'm kind of getting over it but at the moment i have a bigger frustration.
Just another classmate passed away i thought our class had already finished going through this. Our junior year a really close classmate passed and is in a better place and just got shot in the middle of the day. how is that possible? it's just because some guys wanted his bags thats all and because they didn't get it and he didn't want to fight them they shot him. how could they do that? That is a real person with no morals, no conscious, no anything. Brian is the second classmate that passed. He passed because he was racing. I can't believe he is racing, he would never do anything like that. The disappointting thing is that he was racing another classmate and it was just supposed to be for fun. No one was supposed to get HURT!!!!! Someone died!!!
I ask WHY??? I still have no answers and i want answers. HE'S DEAD!!!! I can't get over that. It's so frustrating and i want all the answers so that i can live knowing that he's ok and i know he's in a better place and GOD needed him but we need him too. We want him in our lives and i wanna know why we can't have him??? TELL ME!!!! I need to know but again i won't get all the answers that i want but people can sure try and explain them to me but it's just on me how i accept them and take them in.
