Life Outside Work

Does anyone feel like they have no life outside of work?

i.e. no social life, no friends etc...

I have the week off work and I find that whenever I have time off work, all I think about is work and the stuff I could be doing. 

I find that I feel like I should make plans with people, but that when I do, others are always too busy to make time for me. 

I just spend all my time off in bed.
