Stay off the computer completely - clean your closet - visit your family - see a movie - read a book - get a pedicure - (ok that's me) when you really feel like getting back on the computer , when you're jonesin for it BAD- you may have your batteries recharged and feel like doing it.
If there are any webmasters in your area - get together with them someplace, sometimes simply the discussion, and exchanging of ideas gives you a boost.
Hire someone to do the changes that need made.
when you see them fucking up - it'll give you some push to do it yourself.
I've been there dozens of times - it's a bitch. That's why my business is perpetually for sale (for the right price)
