A Saddened Heart

You know those times where in your heart you know you have to tell someone you love and care for something that you know just isn't going to go well? In your mind you know that they won't take it right away, but your heart keeps tugging and pulling so you know it must be said even though the consequences might be difficult to bear.
Through certain circumstances I am now in this particular predicament. One I love, I have spoken to, and their were not happy to hear it and have now shut me out.
I know that what I said must have been said, but what if I did not say it in the way it should have been stated? What if I am really in the wrong?
My heart is very saddened, and heavy burdened with the thought that this friendship could be over. It was more than a friendship too. I felt as though this person was a sibling, a younger person that I could help. Not that they needed help, but that I could be a confidant, a older sister, no matter what just be there to show affection and support.
I know a few people other than myself feel the same way with their younger friends as well, and I do have some other lovely girls that I do refer to as my sisters (though not blood, they are very sweet girls). But as Jesus said He went back for the one sheep. How can I reach the one I feel that I lost? And was it my fault? I want to reach, but I don't know if it was my fault or not. Should I have just kept my mouth shut and let things be? Wouldn't it have been worse if I never said anything?
