With any change comes disruption in the routine. That’s never really a good thing. Or easy to deal with. One walks around with that nagging feeling of having forgotten something, of lacking something, and/or the anxiety of doing something new.
One’s faced with two options – revert to what was or deal with the change. Once the decision is made, the only way is forward. There’s no use staying in a limbo wasting time. This is the time to be firm. Quite difficult to apply. Darn hard to do.
In the end, one finds oneself with the comforting mantra “You’ll get used to it”. Until then, suffer.
Once one has unconsciously dropped this mantra, then one has developed a new normal.
