I'm sorry you're feeling down, I love my mom and am thrilled that we have the relationship we do, that said I prefer to think of mothers day as a day to celebrate all women. Whether or not we choose to parent.

In a similar vein I feel sad and a little depressed whenever my co-workers (and of course society at large) make a huge fuss over engagements and weddings, my 17+ year relationship is completely unrecognized.
