I understand the challenges, but you need to know that:
a) Many hearing aids are designed to be nearly invisible, especially in-the-ear models. Most modern BTE wires are clear, and when placed next to the skin, vanish very effectively.
b) Most people only notice them if YOU draw attention to them, especially when they are in colors that match your hair/skintone (depending on your haircut, it may be a complete non-issue).
c) People will vastly prefer you wearing them to not wearing them and saying, "What?" all the time.
d) In an increasingly bionic world, prosthesis are becoming weirdly "cool." Make it a part of your persona. "Own it."
