I am so sorry you lost your wife. I wish I could change this for you. Time will heal you enough to go on. Please for yourself and for the memory of your wife take extra special care of your self over the next few months. I know that your wife would want you to do this as much for yourself as for her eventhough she is not physically with you she will always be in your heart. You said that she got you through your heart surgery, she would want you to continue to take good care of yourself. By taking care of yourself like she is looking over your shoulder you are doing the best thing you can do to honor her memory. I am sure that if you had not survived you heart problems she would be doing the samething for herself now without you.
