OMG OCD - You're like a dog with a ball luvely.... You reeeeeally need to find more to do with your time... and there are lotsa options.  These discussion forums are great and there's alot you can learn, and later contribute, for helping yourimprove your ebay experience. Have a flick through the help pages on things like 'revising listings', 'auctions' etc - information is power - what you can and can't do, and what you just shouldn't....

And take a break every so often - go for a walk, cook yourself some gourmet, do some pushups - whatever works ...

I've never heard of eBay burnout before but, hey, there's a first for everything and you're well on your way sweet cheeks 🙂  Just don't forget to breathe...
