I think as we get older and have seen a lot (sometimes too much of life) we can become low in spirits.
I've been through too many traumas in the past year and do sometimes think really sad thoughts about life in general and have flashbacks to traumatic events.
I worry about dying alone, having a breakdown, my children abandoning me, my DIL saying I can't see the GKs anymore, being terminally ill, cruelty to animals and children, you name it I dwell on it.
I watch too much TV but then why not. I keep to happier programmes or documentaries where people have come through terrible times and emerged on the other side.
I thought it was mainly because of the way my life has turned out, but maybe it's part of growing older.
My mum certainly dwelt a lot on her life and she wasn't diagnosed as being depressed. although I think she was.
She would tell me over and over again about things that had happened to her and she found it cathartic. I don't have a person like that, but I have Gransnet.
