The animal is severely dehydrated.
Firstly, 60 second misting every three hours is not that great. Try a two to three minute misting every two hours.
But for now she needs water in her, badly.
Take out one of your plants and put it in the shower. Turn on the water and get it luke warm. Put your cham on the plant and just leave her alone with the water falling onto the plant. I would suggest about 15-20 mins of this. You can check on her ever 10 mins or so. This way she will feel secure and can drink all she needs.
Meal worms are not that great of a feeder, little nutritional value, and the carapace makes them hard to digest.
Go out and get some horn worms or silk worms. Those have high water retention. Even better, soak the worms in water ( don't drown them ) and then offer them to her.
Are you gut loading your feeders? what about supplementing?
Calcium deficiency and the onset of MBD has symptoms of the shakes and seizures your describing. The animal is struggling to support its weight on the weakened bones.
NO NIGHT LIGHT.
Firstly, the red makes it hard for her to sleep. She can see it, and it annoys her.
Secondly, when keeping a chameleon you need to mimic nature. In nature the cham will never have a warm bed and a night light. She needs the temperature drop anyways. It slows down the metabolism and allows her body to rest.
Hot temps during the night, with hot temps during the day - little nutrition from those meal worms, and inadequate misting intervals are your main problems.
Start with the shower first. Do it twice a day, that poor animal is probably dieing for an ounce of water. I can tell because of the sunken eyes, which are basically in the socket.
On a side note, her size is very small for a year old chameleon. Have you had her for the entire year? or just acquired her?

you already posted this thread before, just in general discussion.
People told you in that thread that the animal needs a vet appointment and is obviously dehydrated.
Maybe you should be listening and taking that two hour drive instead of waiting for a second opinion from one of us. No one is going to tell you the animal is fine -
No One
Might I suggest acting responsibly and in the morning putting her in the shower for 15-20 mins and then proceeding to the vet.
If you don't, In all likelihood the animal is going to die.
