Anxiety, Fast heartbeats, Diziness.

I have gone through few good psychiatrists since start of last 4.5 years for my mental health issues. I am fitness freak and I do daily Yoga and meditation. I am facing weird health problems like feeling faint, tingling sensation ( If I don't take medicine), loosing control from body, Sometimes I feel my heart is skipping few beats. In the night I feel very strong heart palpitation so I find difficult to sleep. I am taking Venlafaxin-Mepha ER 75 mg daily one tablet. I have done my full body test like vitamin test, blood test, MRI and ECG but all seems good. Kindly note that firstly I get symptoms then I get worried so my thinking NOT resulting any physical symptoms rather physical symptoms triggers worry, which seems natural. I am over thinker that's true and I get panic easily. I get angry and I abuse in anger but I never hit . I love perfect things. I have IBS issues so I pass gas quite often. I have height 5'7" and weight 76kg around. Kindly suggest am I curable ?
