i want to be happier

My life has become so very boring and very unhappy. I’ve gotten into a marriage that I can’t seem to get out of and I sit in my house and do nothing meaningful with my life. I clean house everyday and cook, and than spend the rest of my time on this computer. I use to be so happy. I use to have friends. I use to socialize and go out to dinner and do fun stuff, but my life has become a dead end, and I want to do something about it. I’ve become motivated but the problem is staying that way, and actually doing something about it.
