Hard-Hearted Hanna

Adventure haunted my nightly dreams. All these so-called whimsical wishes were ground under the malicious spiked heel of Hard-Hearted Hanna, otherwise known as my stepmother . I drew, by Myself, a great deal, but had to dispose of these lest they be found, and when they were, they were immediately classed as lousy . . . Well, up until I was married, as you know, I was nicely toasted and burned on all sides on Hard-Hearted Hannah's griddle, but strangely quite raw and very green on the inside. (by Salter)

Hello,

Q1. Who is Hard Hearted Hanna? Is she the one in the lyric I attach at the end of this post?

Q2: Do the words in red mean she becomes cruel, but still has a tender heart?

Q3: What does "I drew a great deal" mean?

Thanks!

In old Savannah, I said Savannah
The weather there is nice and warm
The climate's of the southern brand
But here's what I don't understand

They've got a gal there, a pretty gal there
Who's colder than an arctic storm
Got a heart just like a stone
Even nice men leave her alone

They call her, "Hard hearted Hannah"
The vamp of Savannah
The meanest gal in town
Leather is tough but Hannah's heart is tougher
She's a gal who loves to see men suffer
