delaying grief?

Kylie, my oldest and best friend and the reason you're able to read this, may be gone from my life, and no idea if she'll be back. It hurts as much as you can imagine, but I haven't been able to grieve - I had a busy shift at work, then had my first session with the weight loss group, and then got about 4 hours of sleep before I got a call from Samantha's mother saying she had taken Sam to the doctor for a severe allergy attack.

At some point, I'll stop and grieve and let the hurt out, but for now its .... bottled up.

I'm not sure this is a good thing or not.
