Pain and Apathy

It is on days like this that I find it exceedingly difficult to not verbally lash out at everyone involved in the military, including my husband.
Without going into detail and calling him every dirty name in the book, then proceeding to throw said dirty name book at the closest doctor at LRMC, today I feel like I am lower than dirt when it comes to my priority in this little food chain of my reality.
I take a back seat at all times to my husband's job, even when I feel like I should at least get to sit in the front seat; (not like I am asking to drive). I have always understood, thanks to my upbringing, that if the government would have wanted their men to be married, they would have issued wives in basic training. That having been said, the military of today does recognize the importance a soldiers family plays in his life, and gives some modicum of thanks and respect.
This terrible creeping feeling is eating away at me; if it was anyone else's wife in that shop who had surgery less than a week ago, and needed to go take care of an errand to improve her pain, they would be out of there like a shot.
Not my husband. I have, for the most part, been told to suck it up... He will get to it when he can, I suppose. That could be 10 minutes from now, or sometime this afternoon. At no time am I to be informed of an exact plan. That's his idea of doing the best he can.
Now, if I wanted to encourage his wrath, by making him look like the world's biggest heel, I could make a phone call to his superior explaining my situation. I am sure they would not only encourage him to help me in any way he can, but would insist upon it- all the while letting him subtly know what a shithead he was for making me "grin and bear it" in the first place.
So I sit idly by, in wait. Even him walking through the door right now will not make me feel any better- as I will be made to feel guilty and wrong for imposing such a torturous and inconvenient errand upon him. Although I did the best I could to motivate the doctors do to better for me, and started my bitchery with the clinic at 7:45 am, I have now forced the inconvenience of the pharmacy trip to the afternoon hours, which means heat and sweat. If not for my complaining, I know secretly he would rather go tomorrow, despite my pain; would that he could... I am far too stubborn, and frankly in too much pain to stomach that.
I hate being a burden.I always have. It does not mesh well at all with who I am- especially not when I am "supposed" to be in the back seat, where a good military wife belongs. UPDATE:
