how you feel is how you feel and you cant change that. when my grandma died about 2 years ago almost exactly (2 weeks before mothers day ironically) i felt so bad because i wasnt crying or anything. the truth is, she was a mean old woman who always yelled at me and told me what to do. i only saw her on holiday's and she was so mean! at the funeral i was bawling my eyes out but only because i saw how much my mom was hurting. i wouldnt have cried at all if i hadnt seen my mom bawling. thats what tore me up more than anything.

the moral of my story is that if you werent that close, then there is nothing wrong in how you feel. maybe it just hasnt sank in yet. maybe if you go to the funeral and see everyone it will sink in a bit more.
