How the Dream Lord's limerick ended

(Found these on Gallifrey Base.)

There was an old doctor from Gallifrey
who ended up throwing his life away.
He let down his friends,
and they came to bad ends,
To his reflection he had nothing to say.

There was an old Doctor from Gallifrey
Who ended up throwing his life away.
He let down his friends
Yet still he pretends
That everything is really okay.

There was an old Doctor from Gallifrey,
Who ended up throwing his life away.
He let down his friends,
But won’t make amends,
No wonder that they never stay.
