I once read that worrying is praying in the negative. The way to create the life you want rather than the life you fear, is to be relentless in releasing your negative thoughts and replacing them with imagining positive outcome. I have never excepted that we create everything that happens to us. But, to the degree we can bring about love, abundance, and healing there is a procedure which works.
Every time a fear comes up refuse to feed it with negative thoughts. Say or think, “I release this.” Then imagine a positive situation, see it as clearly as you can, and then feel as you would feel if this good situation had already happened.
Everything grows by being fed. Feed the positive not the fear.
