Even though your T can't change things with your H's health ... sometimes it helps just expressing those desires
letting her know you wish she could protect you ... letting her know you wish she could change what is going on ... letting her know how you are feeling
it is one place you should be able to be safe to share what you are really thinking without needing to worry about taking care of other peoples needs (which whether we really need to or not can come up with other family)
I hope that the two of you can find ways for her to keep giving you support and comfort; letting you know she is there as much as she can be
