How do I tell my friend what I am feeling?

[unrealy2k]

I have recently as of the last 3 months started a friendship with a girl. She knows that I like her because I have told her, yet we have not dated or done anything sexual for fear of losing our friendship not to mention she is not looking for a relationship in our senior spring of high school, this is just background. Ever since we started hangin out we have pretty much hung out everyday after school. I have been going through alot of stuff lately from my grandmother dying to my dad becoming a quadriplegic, and throughout it all the only thing that has made me happy is her. No matter how I feel whenever I'm with her or talk to her I don't worry about whats going on. It doesn't matter if we are just sitting quitely next to each other or having a deep conversation or just goofing off I am just happy to be with her. I would like to tell her how much she means to me, but I am unsure about how to go about it I usually have trouble expressing my emotions. Thanks in advance
