Hurrah for the paramedics and your hospital for taking such great care of you. I can only imagine how alarming all this has been for you !
Please be patient with your recovery and know that each person's body heals at it's own speed. Also you are on some meds that can cause you to feel tired so keep that in mind. Are you in a cardiac rehabilitation program where everything you need to get and stay healthy is in one convenient location ? If not, do ask your Dr. if you are a candidate for this type of program ?
I wish you peace and will say a prayer for your recovery.
