Clearly this dream made you very upset. It is because it's an important dream. One thing you need to realize is that dreams are symbolic and there is a message in the symbols. They are not meant to be taken literally. So please don't worry, you are not going to die in 5 years.
Dreams are very personal and since I don't know anything about you, I am going to make some guesses with the interpretation. I would guess that you pay a lot of attention to your appearance and what people think about you. At this point in your life, you feel that you are not good enough but you believe you have time to change and become more acceptable to yourself and others. It's about self image.
You had this dream to help you find a different perspective, so you can realize that true beauty is within. True happiness come from the heart. So, do not worry too much about what others think and about your image. Be concerned about your inner beauty and joy. You can use your best wisdom to make choices about you current life situation which will bring the success and happiness you deserve five years from now and your whole future.
Hope this helps.
