In no way are you the only one sweetie, but just make sure you don't confuse being lonely and being empty, they are slightly different. Being lonely is a basic human emotion that is experienced by everyone at some point in their life, more so in today's society because of tv shows, movies, books, social networking, etc. But being empty is the complete absence of emotion which is different, I know this cause of my BPD. You don't care about anything and everything and feel numb to everything and everyone, feeling lonely isn't like that and is completely normal. Things will get better sweetie, good luck xx
