Suffering from psychosomatic disorder.

Hello I am a patient of psychosomatic disorder. Suffering since about 2018. And this I came to know after undergoing treatment in Vellore, Tamil Nadu last February. There after all kinds of medical tests when I was reffered to visit a psychiatrist. The doctor at first prescribed me to take tryptophan medicine but when that didn't give any good results then he gave medicine of mirtaz15 and levipil500 and (lorazepam 20 for emergency). And with that, the doses of mirtaz were given a little higher for the first 10 days and told to take 15 mirtaz gradually after 10 days. However, the first 10 days were very good but since then hands and legs are very weak, feel to stay in home, afraid to talk to anyone, nothing feels good, can't concentrate well on anything, get angry at the slightest, feels like life is worthless etc. But these symptoms were not there before starting the treatment, then there was only mild fever, low immunity, hand, foot, joint vein pain, headache etc. Please suggest.
