Sending good thoughts and prayers your way.
Saying an extra prayer that Your HP and his HP watch over him and guide him.
I know it may not feel so at the moment, but in a day or two or a week and you come back and read this thread, you will finally see that you have done every thing you could as a mom and a concerned human being for your son. Now the rest is up to his HP and him.
If you picture ALL of us in whatever room you are in at the moment, there will not be room for the elephant on your chest and said elephant will just have to leave. We are walking with you in spirit.
Love and hugs,
