No, no, no!
Fear and worry are understandable at times. It would be stupid not to be concerned for our personal well-being, and selfish not to be concerned for others. Feeling concern is a natural part of human goodness. But when it prevents us from accepting our life, fear is crippling. We find ourselves saying no to the world; no to our karma; no, no, no to everything - which is a very painful way to live. When we spend our life wishing it were different, it's like living someone else's life. Or, we could say, it's like living our lives despite ourselves. Meanwhile, the full spectrum of our life experience goes by unnoticed.
