Bored at home what to do?

I always get bored when I am home. I am okay at work because I am busy but when I am home I get depressed or bored. I dont have any friends - I have one but she is not a nice person. Says nasty comments and rather hang out with her ex boyfriend's sister. I was dating this guy who came back and said he really liked me. I keep asking him to come over but he rather work so I am guessing that is not going to work out. I dont have family close. I get bored and unhappy because I think things could be better. All i have is videos to watch and books to read. What do you think I should do to change things?
