Doctors often have to make decisions on incomplete information, in situations of uncertainty or ambiguity. Are you thus capable and if so, validate it by linking examples from your own life experience. It is a judgment call on your part whether or not there is one or more life experiences that have brought you to this point in your life.
As to your last paragraph, I would focus more on how that/those life experience(s) helped me for other decision-making. In the limited character space, you need to convincingly demonstrate to the reader that you have the requisite maturity and decision making ability to deal with such issues. Remember, the reader is rapidly reading very many replies and will instantly have a sense of whether you hit the nail on the head and make overall sense.
I would be happy to review what you consider to be your final work product after you have seriously grappled with this and/or other questions.
