Reptile & Amphibian Forums

I recently came back from a week long vacation and noticed one of my long tailed grass lizards was having issues. She was drastically different, exhibiting an extremely skinny body, sluggish, and not eating. She shows some interest in food but I couldn't get her to eat. Watching her drink, it is clear she is having some issues swallowing. After every drink she has to wiggle her whole body and do some weird jaw thing. She was left in the care of someone who does't own reptiles and would not have observed her long enough to notice such behavior, but all care was done as usual as instructed. Can anyone help? I'm thinking of separating her from the her tank mate which is a male who seems to be doing great. I'm hesitant to do so as it would be very hard to remove her and it would likely be extremely stressful for her.
I hope I'm posting this in the right place I just really need help I don't normally use forums.
