A poem about my autism

This is a poem I wrote years ago. I tried to express what it feels like to have autism.

My blanket

a safe warm blanket
growing around me
to keep me secure
a thick warm blanket
built with my mind

a safe warm blanket
growing around me
to protect me from the unknown
but to isolate me from what's familiar
drifting me further and further away

a thick dark blanket
growing thicker and getting darker
unable to see through
unable to get through
can you help me lose my fear
and make my blanket disappear
