I'm so sorry. Even if you know it's going to happen, it must always be a shock. Sending lots of hugs your way, and I hope you find peace in your memories. Having just gone through this this past week (my Mom), please know that you can and will get though this horrible time. Trust me. Everyone's grief differs, and everyone needs different ways of coping with it. Don't ignore your instincts: if you're tired, rest. If you want to call someone to talk, do it. Whatever you do, DON'T DO IT ALONE! I made that mistake last week. You NEED to talk to someone. Don't worry about "bothering them". I tried to be tough, and it was wrong. I started feeling much better when I talked to people who had been through the same thing. If need need someone to talk to, please, please PM me.
Take care.
