I've certainly gone through periods of time where I wasn't interested in doing any DIY. Usual I just accept that and find other stuff to do rather than try and force myself to do something that should be fun. I've also stopped trying to keep up with every cool project out there, there's just too many and trying to track all of it (not to mention afford it) is insanity in its own right. So my advise, put the iron down for a while, enjoy another facet of life and when it's time to come back to it you'll know.
