I don't know if it's normal, but normal is relative... either way it's not rare. you don't have to cry to mourn
Maybe you just don't cry easily? Maybe her death was expected and you were emotionally prepared for it? Maybe you understand that your sister needs you- that could have helped you accept her death and keep moving forward?
Personally, I think that you accept a death of a loved one when you no longer have unresolved feelings for them or for the circumstances around their death- like if you're still angry at someone or if you dwell on something you regret.. Acceptance is like a fairy tale ending. It would be great, but it's not a possibility for everyone and I think that it's just one of those things they learn to live with over time...
sorry that these are just a bunch of questions but hopefully your answers to them will lead you somewhere...
p.s. I cry easily and I'm crying right now.. I never know how to console someone but.. I'm sorry for your loss.. I can't even imagine
>>3 wtf dude...
