Question: An astrologer said some bad things will happen in my life that scare me. Will they come true?
Answer: The best anyone can do is predict "future possibilities" for you based on your state of mind when you ask someone to predict your future. However, the future is not cut in concrete and moment by moment, through the power of your own thoughts and the choices you make, you have the power to change what the future will bring your way.
If you believe what the astrologer said about your future, it will come true. If you don't believe what the astrologer said about your future, it will not come true. When you believe what another person's tells you about your future, you turn it into a self-fulfilling prophecy for yourself and self-fulfilling prophecies do come true.
