Lisa, I am so sorry this is happening! This time, I can truthfully say, I know how you feel!! When Patrick had this happen, I have never been so frightened in my entire life! My advice?
Keep him laughing!!!
That really helped us. I would wait until I could go home for a few minutes to scream, cry and kick things!! One thing that helped him ... his wonderful cardiologist let me bring Toto to see him!! He even came by to play with her!
We will certainly keep you all in our prayers!
