Rose, I just refreshed the page and have seen your response. What I was going to suggest is something for anxiety if it was possible. The amitriptyline isn't good for your heart.
You need REST. Stop being afraid to leave your s/o alone. I know easier said than done. If I were a doctor I'd say take two aspirin and go to bed. Okay that was meant to be funny. My mom actually said to me a while ago, go to sleep. Easier said than done. Sometimes I think I need a horse tranquilizer to help me. Please rest up Rose. Instead of paper work, let that go for a few hours. Even just shut the curtains at home, shut things out. Put up a stop sign in your mind. How about enya music, or some relaxing music on youtube?
I understand the fear of doc's and new meds and everything. I feel for you. Take something that helps, please, and let yourself take care of YOU.
