Deb -
My husband is a new patient too and I've often felt I was going crazy. I reacted differently than you describe, but I think its our individual ways of dealing with the situation.
For the first few weeks after Mike was diagnosed, I got really weepy anytime someone was nice to me. I also cried often when I was in the car alone - after I dropped the kids off at school, on my way home from work, you name it.
At the same time, I got incredibly angry over the dumbest things - someone parking their shopping cart in the middle of the isle at the grocery store could almost push me over the edge.
No nausea for me - I am apparently bulking up for what is to come by eating everything not nailed down. At this rate if Mike loses a lot of weight we can just switch wardrobes.
Please don't be afraid to talk to your doctor or try counseling if your anxiety continues. The anxiety could very well be causing the nausea and lack of appetite. You need your strength to take care of Jim. There are a lot of good medications that can help, and there is no shame in asking for and getting that help. These forums have been an incredible help to me. I don't post often, but just reading helps, and there are some very inspiring people on these boards that truly give me hope.
I wish you and Jim the best in this battle!
Blessings,
Shelly
