I know everyone is different but I don't have dates. I have a small keepsake but no dates on them, it's made it so much easier for me.
It took time to get past the "i should have been xxx by now" but it did fade away and sometimes I think of the sad days and pause but if I had annual dates in my head/heart I feel it would make it so much harder.
I don't angel tickers for the same reasons, I just don't want to be reminded all the time.
Thats what i was trying to say!
