Sorry to hear of your struggles. Some things I find useful include:

It actually may help to write about the stressors. Many are unavoidable but this may help identify resolution for some of them.

I practice gentle yoga. I'd recommend a good studio that incorporates the mindfulness meditation component. Most fitness centers that offer yoga classes just try to see how many poses they can get through in an hour, and ignore the restorative experience part of the practice.

Mindfulness meditation; this can allow your mind to reflect on the source of the discomfort. It won't make the stressor factors go away but can make it easier to deal with them.

Massage therapy. I find this reduces the physical reaction to stress (tense muscles) as well as the "brain chatter".

I concur with Poetrymom if you have clergy or some sort of spiritual advisor to consult with, that may be helpful.

Wishing you peace.
