Serious question regarding LD…

You guys remember her from some of the older shows? She was mainly on Junior High but appeared in the first few episodes of High as she was getting her cancer diagnosis.

My question is, what happened to her after this storyline? She just eventually disappears entirely after being phased out from what I remember. Did she beat cancer? Did she survive? Did she succumb to it? They literally mention her less & less as DH goes on & by the time School’s Out happens, it’s like she never existed.

Like I’m genuinely concerned about this fictional character randomly. Is LD okay?
