Unfortunately, I am a pro at faking it. And I wouldn't recommend to anyone.
I do it for 2 reasons:
1) Shame and Guilt. I am so deeply ashamed of how I feel that I don't want anyone to know so I do my best to put on a brave face and act like a person even when I feel like a walking corpse.
2) Necessity. I have bills and if I don't pay them no one will. So I have to force myself out of bed and into work. And when there I have to push myself through every second of the day instead of curling into a ball on the floor and crying like I want to.
Faking it can be very painful for me at times. I feel even more isolated and alone around people. I can still feel all the pain inside me but they can't see it and it's agony to interact with people like that. I get resentful that they are oblivious to my pain which is silly since I'm making every effort to conceal it from them! Just goes to show how our minds can play tricks on us ... I guess I have gotten good at this through years of practice. It started a long time ago as a child/teenager I knew something was wrong w me but didn't know what it was or how to fix it so I just tried to act normal. Later on as an addict there were times when I was miserable but was not ready to accept help so I faked my way through the day assuring everyone that I had never been better. I would say please don't try to develop this coping mechanism it's only ever intensified my pain and it seems to me that letting others know how you feel and asking for help when you need it is a much better plan
