<s>[INST] I am Moumita. I am a 20 years old Bangladeshi girl. My height is 5 feet 2 inch. My weight is 60 kg. I have suffered from depression for 2-2.5 years due to some family problems. I took a long time to realize that I was depressed. I went to a psychiatrist about 3 months ago. He prescribed me antidepressants named Nexital-10 mg and Alzolam-0.25 mg for the first time. After a month he replaced them with Zosert-50 mg. These medicines worked but yet I haven t recovered totally. I am extremely suffering from lack of concentration. It has become too much difficult for me to read. My ability to memorize anything has reduced greatly. Now I can not remember many things. My academic performance is bad for the last 2 years. But once I was a good student. The medicines were successful to remove the sadness but it couldn t fix the problems of concentration and memory. I have heard that antidepressant has side effects. So should I stop taking the medicines? How can I regain my brain power? These problems are destroying my career. Please give me some tips(exercise/diet/medicine) to recover. I also have allergy problems. I often suffer from cough, in fact throughout the whole year. My hair is falling excessively for 3 years. I have tried many things but nothing can prevent my hair fall. Hope I shall find a solution from here. [/INST] Hello, Thanks for choosing Chat Doctor for posting your query. I have gone through your question in detail and I can understand what you are going through. From what you have stated it is quite clear that you are having a depressive episode. Depression can occur with regular stress, and it can also occur biologically without any stress as well. You need proper treatment for the same. Its unfortunate that your psychiatrists has switched the Chat Doctor.  Mostly the antidepressants are safe and Robert- sertraline is a very safe  </s>
