I know it's not of much help, because it's how you feel inside about your own guitar playing that's most important, but I can honestly say I have heard a huge improvement in your playing since you first started posting on 12bar less than 2 years ago.
Like your slow blues in G last month - Tytl's comment was "
I go off line for a few months and you turn into a grown up blues guitarist!!! hearing phrasing and notes choices I've not heard in your playing before......great!!!"
and "A Simple Song" - also posted last month - the comment from 12bar of "
Better? Perfect! To me it's the best song you've uploaded ever" was well deserved. And you managed to sustain that improv for 10 minutes, which is incedible. There was a lot of feedback on that thread which supports my view about how good your playing has become.
There is a difficulty of course that with each new level you reach it becomes that much more difficult to get yet more better.
And if you feel in need of a vacation from guitar a break isn't always a bad thing. But I don't think you should do this break feeling that you've failed.
