Hey thanks everyone for the information...I'm definitely learning a lot!
Today they switched a lot of her meds around and she said she felt a lot better (less drugged out, more "with it", no problems with racing pulse). The new blood pressure med is a beta blocker, and she takes it in the morning, whereas she is still taking the minipress (prazosin) at night for nightmares, and she assured me they were monitoring her closely...she's had some issues with low blood pressure and being lightheaded, as you mentioned FlameTachiku. I can't imagine how it must feel for your pulse to go from 60 to 147 all in one day and back again...D sounded really scared when I talked to her yesterday, so I was so happy to hear her sound better and more secure in her meds and treatment today. I'm thinking of all of you who have to deal with this issue.
Also, we were able to chat on the phone today normally for about twenty minutes, talking about both my day and hers, as well as some things other than her PTSD/depression/hospitalization, which was SO encouraging and helpful and happy. Sometimes that issue just dominates the conversation to such an extent, and I get that it is important to talk about, but I think sometimes it just drags both of us down into this cycle of depression and constant focus on the illness.
Who would have known I'd have ever enjoyed talking about work and the weather and her car as much as I did today? It was such a breath of fresh air after the past week, and definitely a success for both her and me, as I feel like I've learned a lot about good ways to communicate with her from the information section for carers here. I'm hopeful, although I realize this is just one up day and doesn't mean everything is "fixed" or ever will be. Still, it was so nice, and I'm not afraid to celebrate the small stuff.
Thanks again everyone for your information/help! I really appreciate it.
Also, Helena--thanks for the kind words. :)
