Puzzle

I know what would solve it,
But im not supposed to do such things.
Reasons are sparse,
But im not supposed to do what stings.

Lock and key is my brain,
But im supposed to unlock with meds.
Side effects choke and struggle,
But im not supposed to hang by threads.

These pieces need to be put together,
But it is supposed to be so easy.
I could find the pieces,
But your lies make me so queasy.

Doctors can put the pieces together,
But im getting numb to the hope.
Electrify my brain to your own content,
But im still scrubbing these lines with soap.
