Why must my mind do this...

I am both an introvert and an extrovert, depending on the company I am in and the personality I am wearing.
I am aware I am a different person around different people and in different situations, I've described myself as a social chameleon before, but that simplifies it.
I was once shy so made an effort to appear more confident and outgoing. It stuck. I became immediately more popular and more attractive to some, and immediately more unpopular and less attractive to others.
My ego and vanity swelled.
I believed my own hype. I slowly realised I hated me, and the bubble popped spectacularly.
Now I'm trying to find an even ground. To at least find a version of me I can like.
