You are absolutely NOT alone. I can remember feeling exactly the same way you are describing. It is very hard when you feel that kind of emptiness. It is harder around the holidays. Just know that you are not the only one and that the feeling usually eases after the holiday craziness. I am happily married to a wonderful man and sometimes feel that lonley feeling for some reason. Take care of yourself and do something special because you deserve it. Good luck with your last bit of high school!
