Do you think severe depression causes all of the physical problems, or is it the reverse?? Since being diagnosed with depression/anxiety. I have had severe stomach issues, terrible body pain, balance issues. There has also been a mark decline in my speech and short term memory. I have had a CAT scan and it was normal, numerous blood tests, even a colonoscopy that was also normal. I always question if there is an unknown medical condition that is causing all of it, including the depression. Or? Is the depression causing the other symptoms.
