A sad story that I have heard from forum users, at a young age you have lost someone who loves you the most in this world. After I read more deeply, I couldn't hold back my tears, I thought your suffering was over, but instead you were diagnosed with heart failure.
I can feel what you are feeling right now, there's not much I can do other than pray and hope for healing for you. Hope you can pass all this ordeal and get out of the operating room safely.
Keep up the spirit @yahoo62278, rest assured, God gave you this trial because he loves you more than anything.
