Feelings don't always make sense. I cry at cine all the time, yet when my grandmother died I couldn't shed a tear. I missed her so much and was depressed, but I physically couldn't will myself to cry. Just because tu don't cry doesn't mean tu don't care. Everyone copes in different ways.
And I'd be happy to give tu a hug, bb. I'm truly sorry for tu loss and I hope tu feel better soon.
Chances are you've either perceived this reciente friend's death differently than the one that happened years ago. There could be many factors causing it, such as this friend probably not being as valued as the last one, o maybe because you've learned to cope with a friend's death so it's not as bad of an experience.
