Hi.. I can see that work pressure is creating a tight feel for you affecting your sleep and mental health.. Bringing in few minor lifestyle changes (i.e breathing exercises,self time, healthy food consumption etc)might help u tackle the stress in a constructive way, thereby preventing syndromal depression. Your effort to seek suggestions is appreciable and I'm willing to help you in every possible way!

Hello..It seems you are over worked and because of too much stress at work,you are not able to maintain a sound sleep cycle.This is causing Anxiety and you are having headaches.

Excessive stress would lead to depression. Try talking to your HR, see a psychologist/ psychiatrist to get help for dealing with stress. Try some relaxation exercises like JPMR yourself. Maintain a routine.
