Don't let the feelings or actions of others interfere with what is between you and your friend in the hospital. What you do now in regards to that person is forever. As mortal beings, somehow we often forget this. You've been given a chance that a lot of people never get... to say goodbye. You would regret not taking it because of what someone else did or said to you. When we find our selves near the end, pettiness ceases to matter. Your friend knows that now. If you can, let him share what he has found with you.
I sincerely wish you strength for what lies ahead. Keep posting.
