I wouldn't hesitate reaching out to her at all. I don't know about you guys, but I've even started hearing more from people that I haven't heard from since my childhood via Facebook. From sharing all these memes and funny songs and videos about the virus, it strangely connects all of us.
Maybe that would re-initiate your connection with her, send a couple of memes her and there. It doesn't have to be personal, but it def shows her a way you're thinking of her to make her smile.
