Well, this is going to need to be handled carefully to avoid any more damage. First step: Get giant cat girl to leave whatever city she's in so she can at least sit down and try to calm down.

Wait she has amnesia? That's a pretty dope concept for giantess art. You can make pretty decent miniseries with that concept. In a city far, far away from her friends and family, having to adapt to being both giant and no memory. Trying to put the pieces together of who's she's supposed to be. Not knowing wheatear or not being giant was something that is normal to her not. Her new identity being influenced by the normal sized people at her feet. Will she become a vengeful goddess or a merciful protector? Or neither caring about good or evil and just be a horny giantess using whatever is convenient to get off.

I’d be happy to help her

You know, it's not very often you see art that touches on it, but suddenly growing enormous would be kinda terrifying. Especially if you don't remember how it happened!
Poor Daryl. :(

This is really nice! I like this premise a lot as well, confusion and disorientation as opposed to pleasure at that size. I wonder how far back her amnesia goes. I assume she's at least forgotten where she lives given that she could just make for her house at that size.
