18. I can’t see it. There is a tendency for people to be unsympathetic if they can’t see an illness but that doesn’t lesson its impact to the sufferer. I suffered with terrible problems with my balance following a severe inner ear infection many years ago and believe me it was horrendous. My ears are still shot, and the problem recurs if I am stressed. The ‘I can’t see it’ scenario is also true of mental illnesses such as anxiety and depression. It’s not a physical illness but it is debilitating. According to Mind, 1 in 4 people will experience a mental health problem each year. So be kind, and supportive if you know someone who is suffering.
