I would be very scared if there was a possibility my meds would have to be changed, too

Whatever's causing your abnormal test results may not be med-related. It may not even be anything significant...
But I know that it's very hard not to worry when you don't have any information, and some very scary things are possible

I hope you will contact your councilor tomorrow. Until then, hang in there BF

BTW, You haven't mentioned your cat lately... is she still hanging out in the kitchen? Could she be of some comfort now?
