how to not be so stressed while chronic issues are being investigated?

i have not had a pain free day in 6 months which is very new for me. i have always been physically pretty fine my whole life. i came off of 3 major meds last year and since then my whole body has been out of whack. menstrual issues, widespread daily body pain, digestive issues, fatigue and malaise every day.. and stress 100% makes it worse. but how can i NOT be stressed out when experiencing all of this and having no answers or help yet? it’s taken so long to get into specialists (i’ve seen a GI once, cardiologist once, will be seeing a neurologist this month, my GP just did an autoimmune blood test panel and i’m waiting for the rest of the results from that.. so far inflammation markers were high though but i could have told you that just from how i feel). i meditate, i try to keep healthy routines and eat well, i take walks on my treadmill when i feel able to, i see a therapist, peer support, and a crisis counselor. i just can’t relax. does anyone have any tips or advice on how to help myself while i wait for answers?
