BT, write down your memories. Try to think of them and when you do, write it all down, just how you remember it. This is the best way I have found to preserve what is important about memories that grow older and will not renew themselves. Keep your written memories somewhere you can find them, and cherish them.
I hope you are doing well now that the day has gone a bit. It is always hard on Mothers' Day. I understand.
We have to become creative problem solvers, not just tolerant burden barers.
