What Causes Stomach Issues With Normal Endoscopy Despite Having OCD?

I have been having issues with stomach for past 15 years. Endoscopy was done twice to check if there was any issue. I have consulted 5 different gastro enterologists in past several years..including ones in National institute of Gastro enterology. Things went on well till one physician told that it could be because of depression I may be having all these issues. on this GP s advise, I have consulted a very famous psychriatist and was told that it is OCD. I was under his treatment for 2 years & was put on all anti depressants. I have had panic attacks, my immune system went down & I under went apendicitis surgeny in nov 2012. In November 2013 I have realised that the Psychriatist had put me on several medicines which may not be required. I have quit all medicines including 2 mg dosage of tablets to reduce anxiety, 3 anti depressants, one antiacid but have been struggling to live nomal life from then but invein. I have left the job & was not working for 6 months hoping that health would be normal but after takingup new job I am unable to perform. I was always a topper and was sent on deputation to Manilla, received several rewards & recognitions in all MNCs I have worked. I would also give you list of all medicines & how long they have been in use for further analysis. I beg you ....plead you to get me nomal. I was not what I am today. Can someone kindly help.
