Been there my friend and its not a happy place as you're finding out. From my experience it would be best for you to talk to her about what you think and feel towards her. No matter what the outcome it will ease all the pressure you're feeling and you never know, she may reciprocate your feelings. Even if she doesn't your long term friendship shouldn't be affected if its a strong friendship and besides everyone likes to know someone fancies them so it shouldn't be bad for her to hear. It may be awkward and a little uncomfortable at first but you have to come clean and see where the dice fall.

Good Luck.
