Rut in a stuck again

I seem to have been in a pretty sullen mood recently.  Not quite sure what's causing it.

I guess part of it is the repeated rejection and failure to get a new contract.  It does tend to get a little wearing after a while.  But that's only part of it

Really my problem is that I'm in a rut.  Haven't met anyone new or interesting for ages.  Not started anything new.  Not made much progress with the things I have started...  And I don't have the enthusiasm to actually achieve anything.  The lack of enthusiasm stops me from having enthusiasm.  Coming up with ideas seems to be extremely difficult and even focussing properly seems to be a lot harder than it should be. Okay - there was the flying trapeze thing, and that was fun while it lasted - all several seconds of it.  Gave me a buzz for the rest of the day; but it didn't last.  And it's expensive! 

So I need to do something new with new and interesting people.  Last time I felt like this I took up trapeze.  The time before I went dancing and before that I did acting lessons.  Running out of interesting looking hobbies.  And even if I find one I need a nudge to actually start.

So that's it.  I need to do something different.  I need to remind myself I'm alive. 

Except I'm not totally certain that is it.  It could just be loneliness. Maybe something else entirely.  This is just a guess.
