Hey @AuntGlow I hope you are well. It looks like I was typing a response to tyme at the same time that you were writing to me! So we actually said some very similar things..
Even though I also think a dog would be good for me on several levels. I absolutely will not get one before going on an extended trip, as it's just not fair to the dog. To go away for an extended time, will likely cause attachment issues and I know how they can affect you. I have seen my dog become unbelievably depressed when his "sister" that is my other dog, with whom he had lived for 14 years (most of his life) passed away. I actually thought he might die of grief. He wouldn't eat, he wouldn't do anything, he just lay in his bed for a couple of months. So I cannot do it.
Yes I am pretty happy with myself that I reached out. I think I sort of thought, what have I got to lose compared to, what have I got to gain. Sometimes when you are very depressed it's difficult to see (or think) that there can be an upside and you concentrate only on the negative. Cognitively I am able to notice and understand these things, even though psychologically it can be difficult.
I am going to see a musical, so that will be upbeat, a friend actually in Melbourne, said she really enjoyed it, so that motivated me to get tickets.
The other thing I did was try out pickleball! Hopefully, if we can find a time some of the people in the group may try and play again.
I do keep a bit of a refective "journal" type thing about things that have been happening. I am fairly aware of things that increase my mood, but it's the sustaining the good mood, or contentment that is the problem. I do have PTSD so there are intrusions that I cannot control.
I wrote a whole lot more in here, but decided not to put it on forum, but have copied for further reflection.
I feel the reasons for circadian fluctuations in mood I have considered and explained in post above to tyme.
I was watching a movie called "One Life" while I was writing my response. It is an amazing film based on true life story and showed how much difference one person with dedication and passion can make. Of course it's a story about an extraordinary person in extraordinary circumstances and most people would not even be in a position to achieve a tiny fraction of what was achieved, but to me I feel it's good to have something to aim for.
I think I have achieved some things in my life which have been helpful for other people and that is I think why I find retirement so hard because I have to find the thing I can achieve now. I am trying with volunteering and lived experience roles, and stuff for my club, but I feel I have the capacity for more, but I am not doing it for some currently unknown reason. I feel I have to push that envelope more.
Sorry long post.
