I feel bored and lonely

I feel bored and lonely. I don't know why. I am health and good looking. I have a good job and income. I traveled around the world. I sing in a choir. I go to concerts and plays quite often. I go sailing and I play social sport. But why I like to stay at my office and don't want to go home. Maybe I should be serious looking for a boyfriend who could make me laugh and who could settle me down.
