I am 41 and will never tell my father. I wanted to, but I rather he think what he thinks of me. He is the reason I didn’t take nary an aspirin until I was 35. His motto was deal with it; sickness is for the weak. He readily admits he would never tell me he was in pain even if he was. He would probably laugh in my face if I told him.
I wish I didn’t have to tell my wife (she’s very skeptical. Scam is too harsh), but I needed to tell her so her mother (a doctor, also skeptical. But because I am not “blood” family. Long story) would refer me to a highly respected psychiatrist rather than some prescription machine. That required me telling her mother. Telling her mother means about another 50 people (All of whom are skeptical, because I am not “blood” family. Long story) know about my ADHD.
