Don't feel guilty. If your friends cared about you they would be there for you, in some way, when you needed it. If they cannot for whatever reason, you can pull back and see if things change. There is nothing worse than a friend refusing to hash it out with you. That happened to me. Total shut down. Friendship cannot go anywhere if one or the other refuses to explain themselves after being asked. Try talking it out and working on a compromise. If that doesn't work at least you tried. Friends are not a dime a dozen, nor are they easily made, as some people suggest. Real friends will hang in there with you. I hope it works out. It's sad to lose a friend.
