Feel like life is going no where....

How do I overcome this feeling that my life is going no where? In general have a great life. I have a good job, make decent money, & have a great family life.... why do I feel like this? I feel as though no one at work cares for me very much and I never get asked to do anything after work hours with anyone. The one friend I do have outside of work does nothing but use me and I need to most likely cut ties. My family is great but sometimes I feel like I need something outside of that. I have never had a relationship and wonder if it Will ever happen for me? I dont even know where to find one or to find friends that actually care about me?? Im just lost....
