I was/am in a mood something like this after reading Godel, Escher, Bach. I can't say I've found a simple way back, but if you're into detailed psych Eric Fromm's books in English were fascinating to read and helped a bit. (Escape from Freedom, Man for Himself, Sane Society)

If you aren't so much into that (or even if you are) professional help is not a bad thing.
