Fibro symptoms after ending a bad relationship

I am reading a book "Moving Beyond Trauma" loaned to me by my therapist. The book is written by a therapist who specializes in Somatic Therapy(body work). She is talking about how our physical body reacts to trauma. I am going through a divorce currently. I have read several articles about how cortisol levels decrease after bad relationships are severed and many lose weight and experience restored health. I take meds for my Fibro and my symptoms are kept mostly at bay. As I was filling my pill case this morning, I wondered if reliving myself of my highly stressful marriage if my symptoms would lessen? Has anyone experienced this? * Please do not downvote me! I am in no way saying “it’s all in our head”, I fought that battle way too long myself!
