sick bearded Juvie help

I was given a juvenile a bit over 1 year bearded dragon as a rescue because they were hoping someone could keep it from dying so I don't have much background they did not want to answer any questions about her. So I know she was not eating much and when she did she shook her head so I am guessing they were feeding her to bog of insects they said it was stuff they caught :/ so in got her and she will not eat any veggies but she is eating the calorie stuff and drinking when I bath her she even will take a wax work or 2. She seems less lethargic but she does not move her cage is 105 she never goes to cool side because she just sleeps. Unless I hold her to feed her or bathe her. My question is could this just be part of brugmation I get she was not taken care of and needs to build up strength but could part of the problem be brugmation. I will take her to the vet but can't until Monday they are all closed any input would be great.
