Any tips for live feeding? What if she still doesn't take it? What size should I get?

I'm about to lose my mind here. I know that going off feed is normal for balls but it's not normal for me and it doesn't suit her personality because she was such a good eater before this.

She does have a good tight hide now. I'll work on bumping up the temps too. Humidity is also good. She just had a nice clean shed last week. I haven't handled her in about a month besides to take her out to clean and such.
