Sorry you feel lonely... You could try doing things that are fun when you're alone, like take a nice bubble bath, have a massage in a Spa, or get your nails done (which isn't necessarily better by yourself, but its still fun when you're alone). A facial, read your favorite book/magazine, or if you have the option to, you could take a class, like an art class. There are also those cheesy quizzes on different websites, like "What's Your Color Personality" and "Are You A Hot Date" try cosmopolitan(dot)com or hgtv(dot)com for some quizzes. These things won't replace celebrating with friends, but maybe it will help you not feel bummed. Hope you have fun, and at least you get to do what you want with no one to argue with!
