Pet store employees rarely know what lighting most reptiles need , the red light is useless so take it back if you can. It sounds like your beardie has no uvb at all, one of the most crucial thing it needed and this is the result. Not your fault, you received bad advice. Your beardie needs a long tube Reptisun 10.0 for good uvb. Get one ASAP, for now take her outside and that will help her right away. Sit in the grass with her out in the sun, will you be able to do that ?
