Medicines problem. And bloating.

I am taking medicines from last 5 years... i started with symptoms of schizophrenia...but i found a doctor who did my treatment and now i dont hear any voices , my forehead headache is gone, but back part of brain is still heavy and sometimes aches a lot...this lifetime good thing happened to me on march 3, 2019... i have repeating thoughts, i think one sentence in multiple meanings, restlessness, irritability and much more from anxiety... but these are not at peak now as before... the doctor who treated me died in an accident so my treatment stopped with that doctor ...and after that i changed so many psychiatrist because i am not getting that level of improvement... escitalopram has stopped working on me, peroxetine gives me panic attacks, fluoxetine gives me fire in my throat, venlor xr 75 gives huge constipation and bloating ... i dont know why medicines dont give me improvement now... and on the other hand medicines are giving me constipation and bloating...
