sad chameleon

Question
Is it possible for my chameleon to become depressed.  She looks so sad.  She looks either depressed or weak.  She does not move from her branch.  I do not think that she has really even eaten.  It just looks like she does not feel like it.  She lays her head on her branch and lets her front legs just hang.  Do you know what is wrong with her?  Is there anyway that I can help her feel better?

Answer
 Most species of chameleon are delicate, and have specific requirements for environment, lighting and food.  If everything is exact, and without knowing her age or particlar species, she should be seen by her veterinarian to make sure she has no medical issues.
