I remember that the Heathens accounted it very base. Plutarch reports of a certain people, who used to manifest their disdain to men who were overmuch dejected by any affliction, and condemned them to this punishment: to wear women's clothes all their days, or for a certain space of time at least, they should go in women's clothes in token of shame and disgrace to them because they had such effeminate spirits. They thought it against a manly spirit, and therefore, seeing they did un-man themselves, they should go as women. Now, shall they account it an unmanly spirit, to be overmuch dejected in afflictions? and shall not a Christian account it an unchristian spirit to be overmuch dejected by any affliction whatsoever? I remember someone else compares murmuring spirits to children, when they are weaning: what a great deal of stir you have with your children when you wean them! How perverse and vexing they are! Children will not sleep themselves nor let their mothers sleep when they are weaning; and so, when God would wean us from the world, and we fret, vex, and murmur, this is a childish spirit."

Ouch! I'm afraid having victory over murmuring is not my strongest suit.
