YR, What you have experienced and continue to experience w/your h in crisis is extremely stressful. However, your medical condition is also playing on your stress level. I would have been very surprised to hear that you had a lot of energy right now. Your body is telling you that you need to slow down, rest so that you can be stronger for the surgery.
I am keeping you in my thoughts and prayers and God will watch over you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
