I'm dealin with this "burnout", myself... A definite first.
I haven't been playing nearly as long as the OP, but I've noticed I just lost my interest for a time. I was initially going hard on practicing, making YT covers, finding people to play out with, etc.. Finally got a nice "weekend warrior" type of gig, and the longer I've played, the less interest I have when just at home. I'll pick one of em up from time to time - Sometimes, I get into it, but most times, I'm done after about 20 minutes. And I used to go for 4-6 hours at a time.
I DO notice I still like to gawk at equipment though. Usually the stuff I can't currently afford lol. Even the stuff I can afford is super appealing because it's new and I don't have it. Makes me wonder if making some changes to my stable would give me that interest I once had back. Very tempted to sell one and put that cash towards something new...
