I'm so sorry

It seems so unfair ... doesn't it
I don't think your message is cold at all. And I certainly don't think it's "too soon". It brings joy to my heart to know that there was a special person like your friend out there for awhile bringing solace and comfort.. Mrs. Bear is right -- that's something to celebrate.
You were blessed to have someone like her in your life. I wish more than anything that you could have had her in your life for a lifetime.
I believe that people who have completed their work here get to move on to the next step sooner than the rest of us.
There's a saying or a belief that as long as someone speaks your name or has a memory of you that you continue on. It's impressively overwhelming to think of how many lives your friend has touched and how much good she's brought into this world.
You were lucky to have someone come into your life who brought love and light and happiness. I wish I could have that.
I'll say a quiet prayer for your friend tonight. I hope that you've got people in your real life that can hold you up and support you until you get to the place where the memories are stronger than the tears. You've certainly got that support and caring from all of us here.
Bless you. And bless the memory of your friend.
