buyer's remorse

Any suggestions for dealing with heavy buyer's remorse? We just closed so too late to actually reverse it. We were in contract for a long time, so I had plenty of time to second guess the whole thing. I'm mainly upset about the precise location (ok with general area) and nervous about the gut renovation we are about to undertake (questioning the potential value, whether it was worth the lower price given the amount of work, etc.). Do I need to just get off SE and Trulia? Everything I read seems to reinforce my fear that this was a mistake. I know some remorse is common, and I had it with my first home purchase to a much lesser extent, but this has been months and months. Thanks.
