There are a lot of changes you need to make to the enclosure. Where have you been doing your research? With months of research under your belt, I am surprised that you thought this was a good starting place. The cage needs way, way more foliage. This is how your chameleon will be able to feel safe. As it is now, she has next to no where to hide outside of the bottom half of the cage -- the half which she should be spending next to no time at all in. Chameleons are arboreal lizards, so they need to be up high to feel comfortable. The way it is set up right now, she can barely perch halfway up the height of the cage. Because of this, she not only will feel vulnerable/stressed, but she can't get even close to the basking spot to actually warm herself. You need to add multiple horizontal branches/vines/walkways for her in the upper part of her cage so she can bask and get close enough to her UVB.
Speaking of UVB, get rid of that compact bulb you're using. She needs a linear UVB like a reptisun 5.0.
Also, she looks extremely young. Probably so young, she shouldn't have been sold. 4-5 crickets a day is not even half of what you should be feeding her at her age.
Please fill out the "how to ask for help" form in the Health Forum section of the website. It would be helpful to know how else you are keeping her. My guess is there are other changes that need to be made, too.
