Different cultures and religions deal with death differently. That does not make you a psychopath. And different individuals deal with the passing of a parent differently, but that is not the test for being a psychopath. My wife is Jewish and she still notes the anniversaries of her parents passing (it was not at the same time) although it’s been about 20 years. I was raised Christian, and while we mourn the passing of friends and family, my family did not normally commemorate the anniversary of their passing. One tradition is not “right” or “wrong” it’s just that sometimes there are culturally and religious reasons in how a death is dealt with. My father died a couple of years ago. I loved him and still miss him, but that does not mean I obsess over the anniversary of his death.

Don't feel ashamed because you deal with grief differently. I'm sure you have mourned and one particular day of the calender does not make a difference in how you feel or how much you miss your mother.

I got called a monster once when I didn't cry when the family dog died. We'd known he was in bad shape for quite some time but a new drug gave him one last summer of freedom and joy before he was put down. I'd made my peace with it in the spring and didn't cry in the fall. Am I a monster? Yes. Does it have anything to do with this? Nope.

I’m same way. It takes a lot to make someone like me cry. I was called heartless because I didn’t cry when my grandma died.

Anniversaries of a death mean even less. Most people don't like the specific day their loved one passed. What a dipshit she is.
