Thank you very much for the useful information Dhruv.
This clearly sounds a depressive illness, and let me also tell you that this is a fairly common problem experienced by most of us (at least for some duration in our life).
You need medical help, and for that a psychiatrist is the best person to get a consultation with.
He can listen to you and take a detailed interview to exactly diagnose this condition, so that an appropriate management plan is instituted in time that suits best to your needs.
Life style modification ---- all are involved in the treatment.
Having said that, let me share with you that the first step towards treating these kind of common psychiatric problems (like depression) is self-identification of the problem. And in your case you have done this and already broken the barriers.
This makes me believe that you will respond well to the treatment and will come out of this condition very soon, for ever, you just need to initiate seeking appropriate medical help.
I would have been worried too if i were at your place but let me reassure you that this is a treatable condition and carries a good prognosis with appropriate management.
It was a pleasure assisting you and thank you very much for visiting us.
