I have had Parkinsons for possibly 6 yrs now and compared to some i manage with day to day life quite well. We all cope with PD differently, it can depend on how progressive the disease is within a certain individual. For a professional capable man who i presume had a lot of control and influence with the career he had, to now having to focus his thoughts on a retirement shadowed by ill health, it's not surprising your husband has been depressed. Retiring in itself is a huge milestone, I retire on Wednesday at the age of 51, reason being whilst i am capable, i want to live and do the things i enjoy in my own time. I found over the past 8 months i have just lived to work and struggle when i do work. My main roll in life is being mother and wife so i haven't lost that, i am still as busy as ever with what that roll entails. I am sure that your husband feels quite grieved for the loss of what he was and what he worked for all his life this coupled with the illness is a double blow!.
Stella you said that your husband had a certain amount of denial about his condition. i suppose that could be said about me from someone looking on because i make no secret about the fact that i limit the amount of information given to me by the medical profession and i ask very little. If i need to ask then i will but knowledge of symptoms that affect PD sufferers that may or may not happen to you would be a long time in my thoughts and worry me, blocking my ability to get on and enjoy the positives my life has in store. So it may not be denial it maybe survival.
When you love someone, to watch them struggle with an illness can be quite unbearable, I would rather have all the conditions that i do have than watch any of my family go through it themselves. Reason being it is simply easier!. I don't wish to sound flippant to anyone reading this, as though PD is easy to live with, but to have no control or ability to improve the health of a loved one must be so difficult to cope with too. The whole family is affected.
I hope your husband finds a way to manage and adapt himself to the things in life that he can do and can still enjoy at this moment in time, not looking ahead too much ahead. Good luck
