Chest Pains. Having non obstructive cad?

On 23rd Jan I had a bad chest pain and rapid heartbeat. I was rushed to hospital. I had 2D Echo, Coronary Angiography and trop T which can normal. Angiogram has myocardial bridge in LAD which was told as benign by cardiologist and got discharged with Metropolol and Olmisartan as I have BP Issues. But for previous month or so I have been suffering from lightheadedness , intermittent chest pains and rapid heartbeat quite often. On 9th March I again went to ER as I felt lightheaded and my BP was 160/90. I had ECG and trop T again and it came normal. After that I have been living with this thing. Whenever I take stairs and whenever I'm stressed or angry I get dizzy and chest aches. Is this due to myocardial bridge? What is happening? Am I having non obstructive CAD ? I'm so frustrated. My angiography report on 23rd January and ECG on 9th March is attached for your reference,
