Migraines

I don't get migraines.  I've only had one in my whole life.  It was awful, the worst my head has ever hurt.  It woke me up in the middle of the night and was so debilitating it took me half an hour just to get to the medicine cabinet for medicine.  It was truly terrible.  So why do I tell you this?  Because Jonny gets migraines.  He gets them all the time.  We used to be able to treat them with Advil, but lately that doesn't seem to help, so we switched to a migraine specific medicine.  So far, it doesn't look much more promising.  And after he has a migraine, he keeps getting headaches for the next day or two, like the migraine wasn't quite enough.  Oh it could be worse, his migraines come about two weeks apart, when they could come much more often, but it is still terrible.  And do you know what the most terrible part of it is, it's that I am a bad mom.  I know that Jonny is in pain and that he really has no control over it.  But I get so annoyed when we have to change our plans so that Jonny can go home and lie on the couch.  I get so frustrated when he is crying in pain because I can't do anything about it, and that frustrates me.  I hate that when he tells me he is getting a headache my response is to roll my eyes and then tell him to go get some medicine and then hope that it was just a little headache and not a migraine.  Where has my empathy gone?  Why do I have such a hard time being loving and supportive when he needs me and when I know that he feels terrible.  And why can't I just make it better?  I'm tired of migraines and I'm tired of being a bad mom, so someone just come and take over for me... please.
