I think today should be the day that you start to change your mindset. And set about trying to change the memory associated with it.
I am sure that you have birthdays that you can remember with fondness. And each year can be a new beginning.
It is all in how we choose to look at it.
So try to look at it differently, T.
You get to spend a lovely dinner with your children. You get to make a wish and eat cake. You get to think about what you want the next year to look like.
It's all in the mindset. Change yours. Starting today.
