Can I set a bit of a challenge for you @Former-Member .... ?
You are such an empathetic and compassionate person at heart, and yet you are standing aside from that for yourself. I don't know whether you have considered treating yourself as worthy of receiving the same courtesy, empathy, compassion etc that you naturally respond to others with ....
Its actually the key to becoming your own best friend, and that might be the puzzle piece you are missing here ....
It you are offering that level of care to yourself, what would you naturally do for a friend grieving an anniversary date ? Buy / pick her flowers ? Go to her house for a coffee or take / meet her out somewhere ? Take some time to try to lift her mood and distract her ? Try to help her discover ways to turn the sense of loss into a celebration of life instead ?
On the anniversary of my mother's passing over, I buy or pick flowers for a vase in my kitchen. I bake recipes she was known for - a cake for us all to share or give as a gift to someone else, make a dish for dinner that she used to cook as a family favourite, place some sentimental things on a tray next to the flowers in the kitchen, light a candle ....
So, on that principle, perhaps this day is one where you can dress in your favourite colour, or wear your favourite boots / T-shirt / jacket / something new .... wear your favourite perfume .... take yourself out for coffee .... with your close friend .... buy a new pair of jeans .... cook your favourite meal .... make or buy a cake, even if it's a cupcake .... put a tray of @Former-Member stuff together to just look at and appreciate .... light a candle.
Try to think of "girlfriend" stuff you can do for yourself. Maybe take yourself to an art gallery, or a movie, and buy yourself popcorn .... go to a coffee shop somewhere else that you usually wouldn't go which might mean a rpdrive to somewhere new .... visit a tourist attraction (be a tourist in your own town) .... go to the zoo or an aquarium centre .... some of these things your phams visitor might be a part of ....
I hope this list is not too long, so as to be overwhelming .... just wanted to give you some food for thought .... and it might need some time to settle with you ....
