It isn't.
I know what "me" feels like and these thoughts and feelings and sensations are none of mine.
It's an invasion.
A violation.
A possession.
Ants that skitter along my nerves.
Electricity constantly running through my brain.
Cancer that spreads through my insides and rots everything that's me.
Leaves me wanting to rip my skin off and strip my muscles from my bones.
Dig out my organs and throw them away.
Cleanse it all until there's only me again.
