What is the true version of you?

We always hear about authenticity on things and people but what is the real meaning of authenticity?
According to Merriam Webster, authenticity is real or genuine : not copied or false. : true and accurate: made to be or look just like an original.
Are you original? Are you the genuine version of you? #liveauthentically

I was raised in a religion where being "holy" is the key to salvation. Most denominations are obsess about being saved, going to heaven. I don't mean to disrespect them. I would like to point out some things here.
I was lucky because my parents didn't push us to adapt that religion that they were in. I chose to be with this denomination because I found the truth. Since I was 15, I went to church diligently on a weekly basis. They were berating those people who are not coming to church. I was also obsessed about being "holy" and being "perfectionist", and walking on the straight line.
I didn't feel that my feet was on the ground. My reality doesn't sync in with what these people in the church were portraying. I was also confused and hard to myself. I kept beating myself for being human."I felt so sinful" - I usually say. That's the guilt and shame right there.
I'm not saying it's okay to sin, to do things that bypasses moral ethics. I am talking about being a human versus being holy. No one can be holy, only God. Why do we have to mimic His Holiness and Divinity where we are only mortals?
Anyway, I kept attending the church until I was 28. I came to a halt where I'm so sick of pretending, not being my true self and being judge with those people who doesn't even feel like "family" to me.
A church should be your second family right? But why I don't feel that genuine connection? They were worshiping with empty hearts and lifeless soul. I went outside the country, tried the same denomination there, it's totally the same. There is no "authenticity". They are not aware of what is being genuine. 
I got out and discovered myself, de-clutter my life, cut those ties that is purely noise and toxicity to me. When I see people going by society standards and it's not even their choice, because of fear of judgment and abandonment, I will say that it's better to be alone than have more friends who doesn't care about you. Who doesn't even know what you are going through right now. Cut those circles who only come to you when they need you and when you need them, they will go cold turkey. It's not being selfish. It's setting your boundaries and self care.
You will feel more confident to speak your mind and you will learn how to firmly say NO to compromises and worthless sacrifice. You have the power to choose who stays within your space. You don't have to listen to what the world says. If they find you weird, crazy, then you are authentic. You will attract people of the same interests, you can tell it's your people.
