Identity Crisis

I have been a size 22 – 24.
Today, I’m a size 2.
A size TWO!!
My primitive brain is freaking out!!
She’s very uncomfortable.
She hates this!
I can feel myself hold back.
I can feel myself pulling back.
I can feel myself with my hands reached out to keep the new me at arm’s reach.
I’m NOT fully stepping into this new me.
She feels strange. She feels foreign. I don’t know how to be her.
How, how, how do I step into this new identity and fully take it on?
