Why is my mother exhibiting strange behavior even after treatment?

Hello doctor,

My mother is 47 years old and used to behave strangely. She used to say that someone scolded her, but in reality, nobody was doing so, and she used to act uncomfortably. So we took her to a psychiatrist, who prescribed her some medicines. Her listening problem settled from these medicines, but another new problem started, and she used to feel discomfort in her chest and whole body. Then we changed the doctor and took her to another psychiatrist, who prescribed the following medicines:

1. Risperidone 2 mg once at night.

2. Fluoxetine 20 mg once in the morning.

3. Clonazepam 0.25 mg twice a day.

But after taking these medicine for one month, she did not feel better, and again we took her to another psychiatrist who gave the following medications.

1. Amisulpride tablet 100mg twice a day.

2. Risperidone tablet 1 mg once at night.

3. Combined tablets of Escitalopram 10mg and Clonazepam 0.5mg once at night.

With this medication, she is not feeling much discomfort, but she has become very much lazy, and her voice has become very much low, and she sleeps all the time. She discerns that she will not get cured now and cry sometimes. Her appetite and digestion are also not that good. She takes Thyroxine sodium tablet 37.5 mg due to hypothyroidism, Metoprolol Succinate 50 mg prolonged-release tablet, and Losartan potassium and Hydrochlorothiazide tablet for blood pressure. It has been three and a half months since treatment started, but she is not recovering significantly. Please help.

Thank you.
