Pet black widow help

So I'm about 5 weeks into having my juvenile widow. Everything has been great and she's growing very quickly. Today I noticed some weird behavior. She fell out of her web when I was putting her cricket in the web. She rolled around on the ground for a little bit twitching, I honestly thought she died. But she hasn't. I helped her back into her web and she's acting like she can barely hang on. She lowered herself back to the ground and she keeps rolling over on her back, she'll lay down and play dead then jump back up before rolling over again. I've offered her water on a q tip but she just grabs it walks on it, then falls over again. I'm at a loss. Anyone have any experience with this or know what may be wrong with her? Video attached.
