Hello I Am 47 Years Male. I Had Mild Fissure

Hello
I am 47 years male. I had mild fissure in march 2016 and was not needed any operation but got healed by applying ointments but later in april I developed some pain in my palate above my tongue so I went to a dentist and she told its nothing but later I had symptom of an awkward feel that there is some hair on my tongue and it became worse so I visited an mds dentist n he said everything is perfect but my symptom was still there so I visited an ent n he told it might be due to acid reflux so he gave me antacids and vitamins but no change.
Later I went to another ent and he told that my good bacteria are missing so its happening and prescribed me vizylac (some probiotic) but by that time my symptoms were changed and I had sometimes burning tongue or sometimes pricking inside inner tongue and since 10 days I also got white patches on my tongue especially when I get up in morning plus the burning sensation and pricking etc. is not stopping so I visited a gastro surgeon and he said same thing that my good bacteria are dead n that’s why I had got fissure earlier so he prescribed me enterogermina oral twice plus folvite vitamin and raciper d twice for acidity and 10 days have passed but I am not getting any better.
I wanted to add that I had anxiety attack in 2013 and I went to a neurologist who prescribed me nexito plus and almost till 2015 december I took 1 tablet daily but from January slowly slowly I left that medicine and thought I don’t want to take this anymore but when this tongue problem started I revisted that doctor and he told me to take nexito plus but the way that medicine helped me in 2013 is not helping me this time.
I also visited a psychiatrist and he said its all bcoz of stress and prescribed me serta 25 (sertraline) and toficalm 50 (tofisopam) and I started that as well but in 3 days nothing was fine so I left it.
I am now confused which doctor I should visit and what exactly is the problem with my body. Is it something very serious and incurable bcoz this problem has put me in heaviest stress of my life.
I have stopped so many things to eat and so many precautions but nothing is helping me
Hope here I can get some solution.
Thanks in advance.
