Hi. What is your age? how many times these symptoms have occurred before & have these symptoms have lasted more than 2 consecutive weeks? I think you might well be suffering from a major depressive episode. Hence, in addition to exercise, remaining busy, you need to take appointment of a Psychiatrist, take medications if required for 6-9 months & you would be able to tide over this crisis very easily. Regards

Hi.
I have gone through your account, and i empathize with you on this.
When you say you have had 3 episodes in last 6 months, it must have been really bad for you. The way you describe the onset of the depressive symptoms is really articulate and gives me an impression you are really gifted in this regard.
Sleep disturbances, memory problems, irritability, headache are all understandable consequences of the depression that you describe. Sometimes, dissociative experiences and feeling of unreality might accompany depression, in which case you might not remember your behavior at a later time. I feel your condition needs proper psychiatric care and evaluation. there are various treatment modalities currently available to help you with the problems, both medicines and psychotherapy. They will surely benefit you.

Also, nausea and headache might be having some other cause and needs to be looked into.

Keeping in mind all these, please visit a psychiatrist and get yourself evaluated.

Hope this helps.

Hi, it appears to be due to the hypertension, or gastric irritation. The feeling of forgetting the next morning might not be a part of the depression. I advise you to consult a physician for diagnosis and treatment.
Practice yoga, meditation, etc diversion procedures, besides medication. Thank you.
