Hello @darweshalassi, and welcome to Mayo Clinic Connect. It must be so stressful to have these symptoms, but no diagnosis!
I'd like to invite into this discussion more members who’ve talked about digestive issues, and who can perhaps speak to psychological issues and whether they have had any physical manifestations such as the chronic nausea you are experiencing.
Please meet @peabody88 @legallyred @jacque6977 @jlfisher56 @bobbiejean @melaniewa @lighthouseceliac @jeffreysgirl13 @astaingegerdm @pamshil58.

I’d also encourage you to go through some of these discussions on Connect:
– Small Intestine Bacteria Overgrowth (SIBO) https://connect.mayoclinic.org/discussion/small-intestine-bacteria-overgrowth/
– Somatic Symptom Disorder SSD https://connect.mayoclinic.org/discussion/somatic-symptom-disorder-ssd/
– Functional Neurological Disorder https://connect.mayoclinic.org/discussion/functional-neurological-disorder/

From what you’ve shared, @darweshalassi, it seems the antidepressant worked; have you considered going back to the psychiatrist?
