Perhaps it's also worth considering that some of the things you saw (I'm thinking mainly of the price increases) bothered you even if you think you are prepared for them. That is a significant change in our daily lives, and I think there is a strong tendency in most people to 'normalise' changes in order to protect themselves from stress. Intellectually we may be prepared, but emotional reactions and subconscious effects might be less than predictable.
It sounds like you handled a stressful situation pretty well to me.
