I'm sorry no one has answered your post so far. I just dont have the experience to help you out on this one. However it sounds like it is both BP and grief that she is suffering from. Grief can take years to work its way out of your system. However all the hormones may have disruppted the medications in your wifes body and they are no longer working well. You need to get her to a doctor to get her meds adjusted and take it from there.
Hope it works out for you.
