Have you done any work with crystals to enhance your clairaudience? Lapis Lazuli placed above the eyebrows is great for opening up the ear chakras, whereby enhancing your abilities. As far as a paraliminal, self esteem supercharger works well for confidence, I have used it many times. Also, Spring Forest Qigong is great for quieting the self defeating psyco-babble of the brain.
Please know that you create your world, and by replacing fear with love, the world you see will dramatically improve. We are all psychic, but many deny or write off their skills at an early age. Nurture and appreciate your gifts and watch them blossom. Be kind to yourself by focusing on the positives, since your thoughts manifest into your reality. SMILE :-)
