She’s on a 90-day trial?  You’ve shared that you’re completely overwhelmed with her care, and she’s not fitting in with the rest of your herd.  Honestly, I’d return her.

Now, I’m not one bit tempted to be rid of my own high-needs horse; but he’s mine, and I love him, and we get along beautifully.  I have very much enjoyed learning how to care for him. 

But a horse on a 90-day trial?  I’d think long and hard about that.
