Hi! Your wife is lucky to have such a caring spouse on her team. 😀 The loss of independence can be scary and frustrating. First, try your best to remember that while you can offer support, you don't have to be the one to fix everything. No one has to carry that on their shoulders. <3 That said, it may be good to sit down with her and have a gentle conversation about what she wants in a support person. She may already have things she would like help with, but is reluctant to ask. Or maybe she just wants someone to listen while she expresses her feelings, without trying to change anything. Let her guide you.
As far as showering goes, if she is not using one already, you may want to consider looking for a shower seat or bench. Encourage her to take her time, and use her oxygen in the shower if needed. It takes as long as it takes, no pressure. And if she needs help, it sounds like you will be there for her, which is a great thing.
I know these are general ideas but I hope it helps. Please feel free to stick around and ask as many questions as you'd like. We are here to support you and your wife on this journey -- we understand what you are going through and you are not alone.
Whenever you want to ask a question, just post it on www.copd.net/forums. Take it one day at a time! Glad you are here. -Melissa, copd.net team
