I so feel your desperation sweetness, just dont get to burn out stage ok, you need to keep your strength up not only for him but yourself as well. What ever is going to be will be, if he is meant to beat this and this is just a expereince, yes a hard one, but if he is to take this journey of a tough road, he will beat it. I know you are feeling helpless, but sweetie try and go with the flow, not saying dont do anything, but yo can only do so much, most important for him is to just "Be" just be with him spend more time with him and continue to shower him with words of love and enncouragment and make sure you get alot of "Alone" time for yourself, you need to havw that time to just be in the moment, this will only strengthen your energy.

I am always here ok, we care about you!
