Unfortunately all the normal things that one might do to combat low mood are not possible at the moment. "The point is to enjoy life" doesn't cut the mustard when someone is truly clinically depressed as this is just what the illness stops them from doing - it is not about making the choice to be happy; it is about the illness taking that choice from you.
Thankfully most people do understand that and have moved on from the pull-yourself-together mindset.
Mary - I think you should chat to GP - phone appointments are ongoing in most places.
I too struggle with the fact that I am now on my own, being newly widowed, but I try and do things that might be of use to others, as this injects a bit of purpose to my day. I bake things for my local children and their families - Christmas cake is in the oven as I write - and I am in the process of making them photos books for Christmas; and something similar for a couple who have left the village - collating photos and messages from others to add to the book.
It is a big leap in life when we have only ourselves to please - especially after lives of caring for others, bringing up family etc. For me I was a social worker in hospitals, bringer-upper of 3 children, organiser of arts festivals and youth music, conductor of choirs, and above all a carer for my sick OH. Now that all this has stopped it leaves a huge gap, and I fully understand how hard it can be to motivate yourself to find ways to fill that gap, especially during these difficult times.
My heart is with you - stay in contact with Gransnet community, and feel free to pm me if that might help.
Take care. x
