I am male 20 years. I believe I am experiencing some problem related to mental health. I have dull mind, memory has become weak, can not concentrate on studies well and forget things easily. My mind seems to be sick and tired. My will power has become extremely low. Most of the time I have stress and anxiety. I am in continuous fear I do not know why, can't find anything interesting, I am afraid all the time! I was not like this a year before! please help me fix each thing mentioned, I am so fed of it that its even stressing me more. Prescribe me medicine if required, if there is anything deficient in my body then tell me. I too am a medical student, please help me so that I can be of help to the world one day too.
