DI've not missed it (used to gig 1to 3 times a week), got on coming next Sunday and feel indifferent about it.
It's the best band I've been in, no big egos, all mates, play some good tunes and try new stuff. Same band for more than 13 years, it's my social life too, we have a good laugh.
However...
Why am I dreading a gig? I've certainly got a lot of stresses at the moment and maybe I think going back to frequent gigs will add to the stresses? I dunno, time will tell.
