It's dark inside

I don't know what happened
to me

I did it only once
and said it was the last

But I don't remember
what I did next

It's like something or one
has control over my head

The things they are doing
,aren't  even me me choosing

I think I know what's going
on ,that drug has taken all
my power

It's hard to remember but I
can't fight them

Without getting deeper
in the darkness

Help me!!
