Doubt it

I let you in
I shouldn’t have
How many days will it take to purge you
I see your face distracting me
It’s there to judge me
But it’s not
It’s all me
I made you up, inside
I know you’ll leave
It’s a matter of time
Still though, I wish though
You would leave me now
I’ll let you in some other time
No doubt I’m sure, this doubt is mine
