I lost both my grandparents... I didn't cry at the funeral, I subconsciously didn't let myself feel.. well, anything. I was numb, like there was a big hole inside me. I probably looked like an awful person to everyone at their funerals. After, I thought of them sometimes, fondly, reminisced, felt sad that they were gone. I cried at all sorts of random shit, films, books, reading things on Bluelight, but I couldn't cry for them. Then a year later I looked through some old pictures of them and it all just hit me, all at once. All this grief, all this anger, everything. I cried for days and days and I couldn't stop.
What I'm trying to say is... don't feel guilty because you can't cry now. People grieve in different ways, you know that you feel the loss, you know that you are sad. It will come. Not in a bad way, it will be a relief. Don't feel like you're not human because it doesn't all come out now. You're not weird, or cruel, or anything like that. You are human, there's nothing wrong with you. Don't worry. Sometimes it's hard to deal with death for a long time, but when you're ready to face it, crying will happen. Until you can cry, remember them fondly, when things remind you of them try and think of the good times with them, hold them close to your heart. You won't forget them, your memory of them will always be there. Don't be afraid you'll lose that, because you won't. Don't feel bad for living your life, not spending all your time grieving. It's okay. When you're ready to cry, you will. Trust me.
