Echoing the value of restš consider the 7 types of rest and see what areas might feel nice for you to incorporate into your day/week rn.
There are some great tools out there (esp. if therapy or doctors visits are inaccessible or just not the right path for you) to support mental health or creative practices. Some free/web available resources I trust are The Artists Way by Julia Cameron (caveat that this has some chat about spirituality, and for some folks that may not be a great fit, but super useful otherwise), Thinking Traps Tutorial by Dr. Raquel Martin or any of her free resources really, and symptom journaling generally. Would be glad to share both wider or more specific reccs if desired.
And just know it takes time but it's not forever that you'll feel dispassionate. Sending lots of gentleness and warmth to you.
