Talk to Psychiatry on Anxiety Probably Due To IBS Or IBS Due To Anxiety

From 6 months my mind is not resting. All tome I have fear that I am sick and I would fall and mn behosh ho jao ga. I feel tightness of chest, shortness of breath, confusion and lack of confidence all the time. I don't want to do anything. The Doctor who diagnosed IBS asked me to not go for doctors instead change your life style. I have changed it I go for exercise on daily basis. I changed my eating habits. I am trying to lose weight as per his recommendation. The doctors always recommended me Levosulpiride and Librax for a month and then leave it. When I am taking them I am alright but whenever I leave them after 2_3 days I start having severe anxiety. I had health anxiety in past I am always anxious about my health and don't want to fall sick all the time. I always google my symptoms and relate my symptoms with different things. Now I don't know what to do because physically I am not having any symptoms but mentally I am not calm. I even fear to ride the bike. No test was conducted
