A Very Good Bad Habit

I am good in building walls,
Shields to keep my mind sane.
I hide my secrets in stalls,
An expert in my lane.

An expert in my lane
Too deaf to hear catcalls
It filters out the pain,
Unmoved like breathing dolls.

Unmoved like breathing dolls,
Clinging to these habits
Until a new one crawls
Into my life in bits.

Into my life in bits,
A very good bad lie
Snugly finds space and sits.
If these walls cave, I die!
