oh man. so sorry to hear about this. I can not even imagine what you and your son must be going through.... I also will be keep you and your son in my thoughts today.
I don't think our paths have crossed yet on this board and I haven't been around here much myself over the past year or so but I don't think anyone can read your post without feeling your very deep, profound pain. It's gut-wrenching. I'm a cancer survivor myself and the fact that some people on this board reached out to me during that awful time really made a big difference to me and it's still something I think about often and was/am touched by (a Mummy Boy Brian F. gave me during that time is a treasured possession I'll always keep). I hope that being on this board helps you even if, understandably, it's only a tiny bit. May your pain lessen over time.
Very sorry to hear this, my sympathies and condolences to you and your son. Despite the fact that we are not well known to one another you are up in 612, so if you and/or your son ever want to meet up for coffeee/cocoa/shopping in the coming months just to get out of the house, lmk.
