Death aniversaries

My aunt died on Oct 2nd in 2002. That was also her mother's birthday (my grandma). They were both special to me. My mom died when I was 8. They helped raise me along with my dad. Sometimes these anniversaries barely cross my mind, but this year, they have really hit me. I'm struggling to function. I go to work and come home, but thats about all I can manage now. It feels like I'm treading water and trying to stay afloat. I hate feeling like this. I know it will pass with time. I need to make it through.
