Oh man, that doesn't sound so good.

Even if we don't know each other well, I wish you a speedy recovery and hope that everything goes well with your 2nd heart surgery. I will be thinking of you during this difficult time and waiting for you to get back to the forum with good news! Even if it is certainly not easy, have a nice Christmas time and a happy new year.
As you can see here in the thread, many people from all over the world wish you all the best and hope you get well again. So much positive energy will hopefully help you get through everything well.
