Being a doctor is a very difficult thing. Sometimes practicing medicine can become a burden that only a doctor can relate to. Many people look up to doctors and say," doctors have great educations, they are wise, brilliant even, and they make lots of money." But trust my words, there are times that no amount of money is worth the task, work, or decision making that a doctor must do. Telling someone that they are dying or have only a little while to live is a very difficult thing to do. Watching people die is difficult. Again, being a doctor can, sometimes be, a very difficult thing. Dealing with death and dying is one of those times that practicing medicine is very difficult. God bless your grandmother. I am sorry about her suffering.
