They only see how bad their life will become in the future! They won't except their diagnose. Diagnosed 1 yr ago with PD, but is on meds and has helped alot but patient only sees how bad it could get. Is on anti-depressant. Always a positive person before Is 85 and won't accept limitations aging has brought on. Keeps asking why me? I don't know what to say. I said think one good thing everyday day, but she says that is so hard to do.
