yahoo62278, you've done something great and I think your decision to tell us about your health problem is of great help and will have a good effect on you. I mean you did the right thing to keep yourself in good spirits even though I know you really suffered for it.
I also have concerns about heart problems because my mother is someone who has heart problems. I nursed her through the years, made her happy, encouraged her and did everything I could to keep my mother have hope of healing. I can't stop worrying about his health condition, it tortures me so much. Even I too often think about something bad when I get a call from a family member because of that worry, I'm so sad about it.
So I really know how you're feel right now, and I hope you really get through it. As a muslim, I believe that illness is a test from God and it is God who will cure the disease even though doctors and medical staff will help you get regular treatment and care. Keep the spirit yahoo62278, you can definitely get through it.
