Put a "beware of land mines" sign. Buy some red paint, shred a few unwanted clothes, shred some big animal bones and scattered all around on the ground. Burn a few patches of soil for greater effect.
I'm gonna be honest, I don't think your parents care if your chameleon dies or not. And the pet shop lady cares more about profit then the chameleon's well-being.
As mentioned by the others, you can give her away to people who can provide proper husbandry or you really need to get some money in...
You have been told to change the lighting more than 3 months ago. So you basically asked for advice on chameleon care and yet you did not change the lighting and supplements, 3 months later you ask if your chameleon is healthy?
I count the adults once every two months or so. Since I always have many males to take out of the colony to sell or feed my other pets. I have a really weird way of choosing the "survivors" and the "discarded".
You know some male adults have this orange-brown pattern on the top of their body...
Also, it's good to introduce new roaches maybe once a year to keep the genetic diversity strong. And when you clean the tub, don't throw away all the poop. Baby dubia eat the poop.
I read from somewhere that insects and other bugs get a temporary stun when the chameleon's tongue snag them. Which means if the chameleon can kill it before the prey recover from stun, it can't attack the chameleon at all. I might be wrong though.
Seriously though, those guys cooked the dubia with sesame sauce and a few other ingredients. One guy finish everything on the plate and he really enjoy it.
Trust me, tarantulas are one of the easiest pets to take care of. I have 4 now, had 10 before.
