I am all by myself

I used to think that I can live alone. Sometimes ago, I have experienced a great quarrel amongst my friends (6 of us) and we have all split into our own paths. I believe everyone has been deeply scared/hurt from that quarrel and misunderstanding. Honestly, from time to time, I do miss those days when we were young and carefree. I feel very lonely at times and  I sometimes wonder if they thought of me. I fear this Christmas I will be all by myself. Deep down, I hope they are living a happy life.
