Hi Rayn, I was just reading the post and wanted to tell you you are not a crazy person for wanting the best for you husband.
I to am a hiker and if all goes well I will hike the AT trail this spring. I kinda look at all this like preparing for a hike. You just don,t take off for the woods with no prep, it is to easy to run in to trouble and not make it if you do.
Maybe you can get your husband to start thinking of this as a trip, there are certain things you have to do to survive in the wilderness. ( cancer being the wilderness) I hate preparing for a trip in the woods,but to survive you have to do it.
The view from the top of the mountain is beautiful and it takes hard work to get there , but most people think it is worth it.
There are many here that can give you all the info you need , and many of us that will be praying for The Lord to move your husband in the direction he needs to go. Have courage, Rocky
