This thread is absolutely heart wrenching, and I keep coming back to it. I wish I could do more, or find the right words to say-but there are no words to ease the sadness. I can only speak for myself, but like so many others here at DC, I am happy to be here for you Mikki-Just a few keystrokes away.
FWIW, the site mentioned by PieSusan is very very good. You can post a memorial to Tyler, they have lots of good support resources, and every Monday they have an on-line candle service. I know it sounds silly to some, but for those of us who feel, or have felt as you are feeling, its very theraputic.
You are in my thoughts and prayers.
