I am a student. For some months, I have noticed that my mind is playing tricks on me. It is more like every day I have a down phase which lasts for two to four hours when I feel all negative emotions are coming to my mind. I think of anxiety and fear. I feel like I have a beast inside my mind to which I have to fight to make myself in a normal state.
First, I thought it was depression, but it is not lasting for whole days, not it continuing for months, but more like two to three hours of down phase. I have seen people with severe depression, where it is difficult to get out of bed also a difficult task. This is not for me. At least I can talk to people, and I go to work every day.
For me to feel better, I have to sleep or distract myself with songs. I thought it might be bipolar, but I am not sure. I want to know can it be symptoms of mild to moderate depression, or is it bipolar or any other mental disorder or it is due to stress?
