Welcome Michelle,
I'm so sorry you got the diagnosis that sent you here -- but I am certain you will find this place soooo helpful as you maneuver the new life you have been led to.
My daughter, also Alyssa, was diagnosed just about 4 years ago when she was an infant. It was so difficult when she was so little, mainly because there was so much I didn't know. It felt like I was dumped in a foreign land without knowledge of the language and without a translation dictionary. I was worried and scared for my daughter all the time....but with knowledge and time it has gotten easier. My Alyssa is a beautiful, smart, energetic, and MOSTLY healthy normal 4 year old girl now. We have our moments of health issues, but overall things are soooo much better than my imagination led me to 4 years ago.
Once again, welcome!
