So I have this best friend. We've been best friends for a really long time. Recently we've been doing a lot of things together like going out to lunch, hanging out after school, hanging out on the weekends and stuff like that. I have now come to the conclusion that I have a major crush on her. I don't know what to do... I want to tell her how I feel but I also don't want to for fear of rejection. Can anyone help?

Life is cruel, if you want a response from your best friend you will have to take a chance, even though a rejection might come keep going! (But don't overdo it)
It's not romantic with someone giving up instantly and if she rejects you it will start a chain reaction of thougts, she might come to like you, if she doesn't.
Talk too her, but if you do that, you will probaly not be able to go back into that "best friend" relationship anymore.

Try tricking her to tell you if she has a crush for anyone if you don't know the answer already, I mean, if she tells you that she has the biggest crush of her life on a guy/girl that seems to like her back it might not be a good idea to confess.

I hope it helped if even a little!
If you tell us more about the situation, your relationship we might be able to help more.

You can try show her that she means for you more than a friend, let her see that there is something going on before you talk about it.
I'll think about more (like examples for this idea).
As Terroth said if you tell us more about the relationship we will be able to help you more. Also if you want i can give you my skype id so we can stay in touch (i check my skype twice a day, and the Dollars page once a week )
