Barb and Sherrine: I hope things are going better for you both! Stress is so sneaky, and it's hard to avoid it, especially these days.
For me, prayer is really helpful. There are sometimes some things "too big" for me, as when several things go wrong at the same time. I do what I can, then I've had to pretty much say, "Okay---this is all Yours, Lord. I can do no more." I do find prayer comforting, in general, and I know some others here do, too.
This next point isn't necessarily about
stress, but more about
anxiety. Dr. Claire Weekes wrote several books years ago. I just checked online, and they are still available (or you could probably get them at a used book or thrift shop for next to nothing). Just do a search on her name.
She has a simple step-by-step program: Face. Accept. 'Float' by (unwelcome thoughts). Let time pass. Her books can tell you much more. I found them helpful and a very down-to-earth approach towards getting through difficult times.
It wouldn't necessarily "work" for some stressful situations, but might be helpful for others.
Prayers for you both! I hope your situations have gotten better. Take care and best wishes.
