Too scared to tell my friend about my feelings.

I feel so silly writing this… I wrote another post in this category about questioning/dealing with my feelings towards a good friend of mine. Well, I finally accepted that I love my friend, but I'm too scared to go see my friend and tell them how I feel. It's possible that my friend already knows how I feel, but I don't know for sure. I've had many chances to go see my friend, but I keep chickening out. We've always had a very close and affectionate relationship. I've told many personal things to my friend before and my friend has always been so supportive and understanding. It's a very special relationship that we have and I can't help but to worry that I might ruin it if I were to confess my love. Yet, I don't want to keep it a secret for the rest of my life. I honestly can't see myself being with anyone else. I don't want to be with anyone else.
