i'm losing

what do you do when a friend changes right in front of your eyes? its like you can see all that they were being stripped away and replaced with this person that you are not even sure you like? how do you confront someone that is not even aware that they are changing? how do you let them know that you love them, but that you don't really like this new person they have become? if overflow of the heart comes out of the mouth then i am terrified that this heart has been changed for the worse. how do you pray for someone to be something else? how do you let someone know that you love them so much, but that you are scared that maybe if things keep heading in the same direction that that could change?
