Do
you have to be the creator every time?
If your bass player and drummer are good, why not let them play faster/ more complex stuff and you just comp for them? A rule of thumb is that the more fast and complex the bass and drums, the simpler your guitar part can be. It can be repetitive litle lines like a horn would play, with lots of repetition. It'd depend on the style of course. Hell man, you could vamp on an E9 chord for quite a while in the right context. Muted strums, sliding the chord, etc. Let the bass player slap and pop. They love that stuff.
Or even litlle 3 note melodies with muted notes.
Just some ideas if that helps. I'm most creative playing alone, and take grooves along to play with others, but sometimes playing with good people just brings out ideas, you know? When I get creative while nervous (which I have a habit of doing), it often doesn't come off for me. Best to experiment (make my mistakes) at home...or at least have a fall-back like Knight 46 says.
It just sounds like your expectations are really high, and you were cold.
Oops, sorry, just you and a drummer? Yeah, that's harder. Less to "bounce off."
