Mibs, I sympathise with with you having a partial hearing impairment. My son in law is profoundly deaf from birth, and it has restricted his job opportunities due to ignorance and discrimination on the part of employers, even though he is bright, and has many marketable skills.
Maybe God, throws each of us a challenge to see how we cope with it, and to see how others relate to us in our needs.
Acceptance rather than anger is the first step towards healing, and the greater healing is not necessarily what we presume it to be.
