I am so sorry to hear this, please know that my prayers are with you. You have been a positive influence here (or at least on me) and it it's hard to see you go through something so difficult. I'm sure you realize you have many friends here who will do whatever we can to aid you in this time.
Its hard to believe but those are the words you wrote to me on this board almost nine years ago. I return them to you now in hopes that they will mean as much to you today as they did to me all those years ago.
If not already, you will soon realize that no one really knows what this is like. Not even those who seem to have similar situations... because really there are no similar situations. There are too many variables and too many differences. But you will overcome. You will do it because of your strength of spirit. And you will do it for your son.
My prayers and thoughts are with you. Let me know if I can help.
