Fatty liver and rapid heart rate change.

I got a test for lower abdominal and docter said I had fatty liver of grade 2 and gave medicines for that, even after taking medicine for more than two months it don't seems to be getting fully cured. My issue is when I eat sometime my BP increases and I feel restlessness and and when I burp or pass gas sometime it seems to be better. I had issue of triglyceride too and also less vitamin D . I am unable to understand what is the issue. I had to visit hospital in emergency few times as I thought is had pain in heart and may be issue with heart but tests related to heart came normal. some doctor said it's due to cholesterol and triglyceride some.said it's anxiety some.said it's like depression some said it's related to.liver some.said it related.to BP I am really confused what exactly is the issue. I have also noticed that when I walk faster I my heart rate tends go up rapidely and I may faint sometime.while speaking inyensibely i feel restless,Can anyone suggest what may be the issue
