I think I fake my expressions, my personality, my style, my words &amp; my thoughts and I don't know if that's normal or not.

I am a liar. When I feel down or I am splitting or I am angry, I feel like deep down that I am faking it and I feel like every feeling of mine is a lie. Every act, every thought. Everything. 

I don't know who I am and why do I think like this.

It feels like I'm watching myself play a role in a theater. 

TL;DR I think I'm faking every emotion of mine to get attention
