Karen the road you travel is long, frustrating and very sad. I walked it with my Dad. I pray for your peace and acceptance of Gods will. You are so loving to give Mike 100% of your best every single day. Please give yourself the credit you deserve . Take time for yourself and know others are walking this path with you through prayer and thoughts.

Hi Karen, I am so sorry to hear this. I am sure you have exhausted all possibilities for studies. But, in case you haven't seen this one at Mayo, I am sending you a link to a study that is open currently for people to join if they meet requirements.

Karen, I'm so sorry to hear this, it must feel like your last hope for help was taken away. May God grant you and Mike strength each day to continue on this journey. We know that He loves you so much and hears your prayer. We think of you each day -- let us know how we can help.

I pray God finds you a way to escape your sadness, even if it is only for moments today and everyday. Mike is blessed to have you who continues to love him and to ache in his agony.
I don't know what I can do to give you a break from your heartache but if there is anything, run an errand, bring you ice cream from DQ (ice cream always makes life better) please text me.
