Still there, at least?

I've kinda(an understatement) lost track of this one.so I'm hesitant to put this one into words. Yet I still see her in passing I still want to say hi(too distracted usually) and she's always with someone new And/or she looks different(possibly makeup). So idk is she there or am I as nuts as it sounds. Likewise since she often looks different how can I tell it's her?; (again).
