Feelings of my heart

I don't know why this happening but lately I am feeling alone and lonely on regular basis. I am in a middle class govt. Job and getting approx 5 hrs. Free time in a day. I get really alone in this time . I don't know what to do it didn't happen before. I am preparing for bigger exam also but as schedule is not fix it's really hard for me but after some time I will start to study.
