Is it just me?

Am I the only one that HATES their own company. Like I can't stand being on my own, especially at weekends. I can't help but feel so lonely and it's even worse when I know my friends are doing something and I'm not. I can't concentrate and do something like read a book or watch tv etc cause I just feel so lonely. I've actually (embarrassingly) cried and got so angry and hysterical. It's not so bad lately but I know that next week all my friends are doing different things and my boyfriend is away and I'm terrified I'm going to be bad, I've already thought of things which I can try and do to take my mind off it.
