Hello,
The problems that you have mentioned here seem to be causing significant distress and effect on you. Which would suggest that you should seek a consultation with a psychiatrist near you at the earliest. Such problems can occur due to either biological/medical causes like brain transmitters/
thyroid/anemia etc, or psychological causes like impaired coping skills, cognitive errors etc, or social circumstances like job, family, friends etc. Hence a comprehensive assessment is required to exactly understand the factors behind your symptoms. Therefore I would like to suggest that you seek a consultation with a psychiatrist for detailed assessment.
In the meantime please talk to your family and friends, keep regular sleep and wake timings, eat healthy, go for some light physical exercise like walking or jogging, engage in some pursuit of your choice, and please be sure that your condition can be improved if things can be sorted out..
Hence please consult a psychiatrist near you.
Hope this helps you. Best wishes for your health and future.
