It seems that you undergo a lot stress due to your profession which causing all those physical symptoms.
Do visit a Psychologist and consult and share your emotions which u feel and learn to manage your issues.
I understand how difficult it must be for someone from entertainment industry to be experiencing these symptoms, where there is a lot of public dealing. By the description that you have given sir, this most likely is an anxiety disorder with panic attacks. With the current level of symptoms,the ideal thing for you would be to take treatment with a combination of medicines and cognitive behavior therapy. However, the best long term management would be on cognitive behavior therapy only.
Meet a psychiatrist at the earliest to begin the treatment. You may contact me for a private consultation as well if you wish.
Pls avoid using smoking or alcohol as a source of relief for your condition.

It is treatable with counselling and medicines for a fixed duration. Analyse yourself and maintain dairy so that the professional will analyse your problem and give the best solution.
