Thanks for using this forum...
Depression and anxiety move hand in hand...You should cut down on your tobacco and alcohol consumption as itself can lead to both these things..One or two bad days do not meet you are back to square one..You should do some stress relieving breathing exercises and activities to keep you involved to avoid resurfacing of depression...Meet more people and go on frequent breaks to avoid the monotony....You can have sessions with the psychiatrist to help you out...
take care...
