Hi. The symptoms that you have mentioned are highly suggestive of underlying depression and anxiety. Even your memory loss is due to your inability to focus and concentrate which leads to inability in recalling things. It would be prudent to undergo a complete psychiatric evaluation to reach a definitive diagnosis and accordingly initiate treatment. Depending on the diagnosis, treatment would include medications, psychotherapy or a combination of both.
Next Steps
Seek a psychiatric consultation.
Health Tips
Start exercising daily. Also start writing diary daily to vent out your feelings.
