Losing interest and passions, why won't they come back?

If im honest i just really want to do social activities because Im fed up of spending so much time on my own. Therefore everything else seems dull in comparison.

When I watch a dvd i think there are probably groups of people at the movies.
When I cook I think there are people out to dinner
When im on the internet I think there are people out at parties/bars/just hanging out.
When I go to sleep I think some people have relationships.

So i think im just sick of solo stuff in a way. If there were social things to break them up....I'd probably enjoy them again as a treat rather than as my only option!
