I just read this all... and I'm so sorry. That is such a hard thing to go through. =/
I know it's not that helpful but I still wanted to let you know that I'm sorry for what has happened... I really hope that you have a strong support system to help you through this and everyone else in her life that needs help through this.
Thank you. It is helpful actually so thank you again.
I have a pretty strong support system: My parents, sister, brother and all of my friends. Her boyfriend, some other friends, and I are all getting together tomorrow and we're going to talk about all of the memories we had with her.
