Cushings Disease- cortisol withdrawal?

I was diagnosed with Cushings in early 2021 (pituitary adenoma). Before I could have transphenoidal pituitary resection to remove the adenoma, found out I was pregnant. In July 2021, at 18 weeks pregnant, I underwent my first surgery. My cortisol dropped and I experienced adrenal insufficiency 2 weeks post-op. My symptoms subsided and I had a healthy baby girl. Two years later Cushings symptoms returned and labs showed very high cortisol again. I underwent a 2nd pituitary surgery in December 2023. While there was no actual adenoma found, my neurosurgeon removed more suspicious pituitary tissue. Post-op cortisol levels remained high and symptoms continued...along with a plethora of other symptoms that I didn't have before (hypothyroidism, zero estrogen, etc.) After discussing cortisol reducing medications and pituitary radiation, it was determined that a 3rd pituitary surgery was my best option for a cure. I underwent the 3rd pituitary surgery in November 2024. Recovery was absolutely terrible. Cortisol levels remained high for about a month, but I experienced a crash in mid-December. It seems like since then my cortisol levels have fluctuated quite a bit, but I have also been on and off with hydrocortisone. The past 2 times my levels were checked though, with no hydrocortisone, they have been right in the middle of normal range. My question is- has anyone experienced cortisol "withdrawals"? I have been having horrible episodes of racing heart, extreme temperature fluctuations, paralyzing anxiety, feeling like I am literally going to lose consciousness, nausea, headache, body aches, etc. Many of the same symptoms as adrenal insufficiency, but my labs do not show this. I just had my first appointment at Mayo Clinic and met with a wonderful endocrinologist and she mentioned that I might be experiencing cortisol withdrawals (waiting on more lab results to confirm this). But I am just curious if anyone else has had this and what your symptoms were. How did you cope? Do the episodes eventually stop? I think it would even help just to know that there is an end in sight! Any help or advise is greatly appreciated!
