We're here for you, tigercat. My brother's best friend was killed in an accident 21 years ago this past October, when he was in 6th grade. We were next-door neighbors. I still remember coming home from a camping trip and finding out the news. I still grieve, especially around the anniversary date. I simply cannot imagine what a parent goes through.
Try to keep your spirits up, and vent away when/if you feel the need.
