At the time of the April dock search, Hardy made a statement that Misty was calm and for the first time realizing she was in trouble. She could have become calm with anti-depressant/anti-anxiety meds. However, when her skin started breaking out, they took her off those meds (per her conversation with her dad). It's unknown if she was put on another medication or if she was taken off meds completely.
If Misty needs medication and is not getting it, that could explain her appearance and her demeanor in court. She looks disinterested, like she has given up, but that's just what I see in the photos of her in court. It is difficult to say what's going on just from a photo. Clearly, her physical appearance is not good and it is not unreasonable to assume her mental status would also not be good. Either she needs medication and is not getting it, or she is on something now that is not good for her and needs at least a dosage change. Psych meds are not "one size fits all." A person may have to try many different meds at different doses to get it right. That process can take weeks at least for each drug tried, and possibly that is what they are in the process of doing for Misty now.
Misty goes back to court in July; it will be interesting to see if her appearance and demeanor have changed because we should see an improvement by then if she is being properly treated.
