I'm glad you're coping with a very difficult situation. Jumping on a bit of a tangent I'm fascinated how you swap between 'I' and 'You' in your comment and how it could read differently:

"Be gentle with yourself. Know that you can be scared, frustrated, or angry but don't have to let those emotions define you".

could become:

"I'm gently with myself. I know that I can be scared, frustrated, or angry but I don't let those emotions define me".

The difference is interesting to me.

Edit: You just inspired me to rewrite Desiderata in the first person. I'm not conceited enough to believe that my version is doing more than faintly echo the original text but it was a (self) enlightening process. Thanks

I move placidly amid the noise and the haste, and remember the peace there may be in silence. As far as possible, without surrender, be on good terms with all persons.

I speak my truth quietly and clearly; and listen to others, even to the dull and the ignorant; they too have their story.

and so on.
