A few years ago I was also bereaved (not a child but a much-loved person in my life), I was reeling from some terrible family dynamics, I had a lot to deal with in my own family, I was obviously depressed, I was in menopause as well.
I wrote a list in my notes app of all the things that were wrong, and what I could do to address them - action or mindset. I found it yesterday and it is amazing to see how far I have come from that point.
I had a separate list for things that I knew would bring me a glimmer of joy. The simplest things like being outside for a little while. A ten minute walk.
I also had a list for what exacerbated my state of mind. Doomscrolling, bad eating, etc.
I had a list of favourite nutritious meals, for when I couldn't think about food.
A quiet song playlist, which was really calming.
In one of my lists, I wrote this: "remember that in a dark moment, you sat down, thought all this through, and documented it to remind yourself later. You’re not useless xxx"
I feel like this all sounds quite trite but honestly, it helped me to know that I could just check those lists, I didn't have to think about things from scratch. A form of self-care. All the very best to you xx
