My apologies that your question did not receive an earlier answer. Your patience is greatly appreciated.
I'm so sorry Chanci is feeling miserable. The crying definitely means something is wrong/bothering her and could be causing her pain. She may have a bad tooth or other oral/dental problem that is causing her pain.
Because she's twitching her ears, she may have an ear infection, which can be very painful. In addition, she may have ear mites which will need a miticide to get rid of them. Of course, if she has an ear infection, she will be prescribed ear drops for the type of infection that is found. Cats can develop bacterial or fungal/yeast infections in their ears.
She also may be twitching her ears because she has fleas or mites (which are typically microscopic) and they are very itchy and causing her pain.
**Human pain medication is toxic to cats and I would not give her any human anxiety medication unless prescribed by the vet.**
One thing you can do at home, before she sees the vet, tomorrow (Monday), is give her an antihistamine like Chlor-trimeton, which has a sedating effect in most cats. Benadryl is another possibility, but it has a very bitter taste and makes cats foam at the mouth. The Chlor-trimeton is a very small pill and if you give her 1/4 of a 4mg. tablet, it will be easier to pill her. You can crush it finely with the back of a metal spoon and then add it to a little bit of her canned food or some plain jarred infant baby food chicken or turkey containing NO onion or garlic products. You can even not crush it and give her the 1/4 tablet, whole, in a small 'meatball' of her canned food. After she takes the medication, follow it with more food and water. Here is more information:
I hope this helps her sleep until you need to bring her to the vet's office, tomorrow morning.
Another product that will help relieve stress is Feliway plug-in diffusers. These emit cat-calming pheromones only detected by cats; they have no odor to humans. Here is more information:
I hope all will be well with your Chanci!
