Welcome to the forum!
Sorry that your cham isn't well.
It sounds like she really needs to be examined and treated by a vet who treats chams or at least reptiles, as soon as possible.

Daytime sleeping means she is sick and needs to be treated by a vet with chameleon experience or at least a lot of reptile experience.
How do I know this?
In nature, chams must hide all signs that they're sick, so that they don't become someone else's dinner.
Because of this need, they do all that they possibly can to look healthy even when they aren't.
Healthy chams never close their eyes in the daytime and they don't sleep in the daytime.
Doing these things makes them very easy targets for predators.
Her weak grip is another sign of illness, as is the bump on her face.
We might be able to help figure out what caused the illness if you answer the questions from the how to ask for help form that crazychamzoo posted but a visit to the vet ASAP for medications is what she needs.
