It’s very important to do self-care, keep balance, share your feelings by not stuffing them (in a journal, to God, to someone else, etc.) and find things in your life that bring you joy. I had many years in my marriage where I was alone, and God provided other areas to meet my needs. Find areas where you can fill yourself, areas you can pour into the marriage, and ways you can be with others. Crying out to God, praying, and surrendering the situation to him is also very important. I also think grieving the relationship and what you expected it to be is important too. Find friends also in crisis, maybe not in the exact same situation so you don’t try to fix each other, but just where you can listen and walk alongside each other. We have five people who have given us their house keys so that we can crash on their couches. We don’t use them often, but they’re there when we need a break.
