B9exchange a bit frustrating must be the understatement of the year!
As you get older it's impossible to not think about death. All you can do is get your affairs in order for some peace of mind. Then enjoy life as much as possible and try to not dwell on it. It's difficult if you have health problems that stop you going out and mixing and doing things you like.. Then you have to really fight to stay positive. (I'm so glad we have Gransnet.) People don't like to talk about it as they might depress their partner. Getting old is not for the fainthearted.
Sebstar what I do is try to book some treats like theatre or concerts. I don't always make them but something to look forward to helps. When you get a sunny day take a picnic and go somewhere nice like a NT property.
I don't actually know what doctors can do about this?
I've got another 'keen'... Ouch!
