Was my entire life fake?
No. Your life is/was very real. You have to begin the process of deciding now if it will become fake though.
We live our lives within a system of belief about things. You believed at the age of 2 that mom and dad would always be a part of your life. At some point, though, be it death, divorce, or a break from them emotionally, you gradually accepted that you would not always be living under the roof they live under. You views began to evolve so that you took yourself out of the 'protective custody' of them, and began to live your own life. Your life had not been 'fake' until then. It just changed.
Anyway - not a well thought out simile, but you get the point. The danger is now that you are fighting two diverse opinions about life - yours, and the WTS teachings. Just like with your parents, there are certain things that you will take along for the rest of your life from them. There are some things that, as an adult, you just cannot agree with.
The WTS teachings can be ok. Not all of them are bad. But the belief system is flawed. The idea that they have the 'truth' is wrong. You have discovered that - and you can never un-ring that bell. You now have to decide if you can live under the same roof, and if you do, you will become somewhat 'fake' now. You have already begun to experience that. It will get worse as an elder at some point. You might find that you are unable to recuse yourself from JC meetings in which you will be expected to ruin lives if needed to 'protect the organization'. Will you be 'real' or 'fake' at that moment?
I can't answer. Only you can answer. Your past was not 'fake'. You were deceived. Will you counter with deception? Or will you find a way to extricate yourself and be 'true' to yourself?
There are no pat answers ahead. I offer none. But there will be some gut-wrenching decisions in your future I suspect.
Welcome to the board.
Peace to you
