"You have five minutes to wallow in the delicious misery.
ENJOY IT. EMBRACE IT.
Sanity-saving strategy right there. Good to last from half a day to a whole one. No need to worry though, because once the effect wears off, you can simply repeat the process.
I heard those quoted lines, by the way, from the movie, Elizabethtown, which is surprisingly not a very good film despite being directed by Cameron Crowe. It does have its saving graces, however, like a couple of inspiring quotes such as the one stated above.
Now, I'd been meaning to try this little strategy out ever since I heard it a couple of days back. Finally, the opportunity presented itself yesterday, and what can I say? It works. Big time.
Even if the effect isn't permanent or long term, it's long enough to help me go along the rest of my day with at least half my sanity still in tact. Anyway, it's a rinse and repeat kind of strategy, too, so you can just keep doing it once you feel the pangs creeping up on you again.
It really is much better, methinks, to allow yourself first to feel the pain and grieve before moving on than to believe you are devoid of feeling any of it.
