Should I reach out? I feel bad but also not

So I ghosted someone a few years ago... It was a long distance friendship, we had been friends for a few years but I just found her conduct the last time I saw her to be very much.

Firstly, she comes here on holiday, I am working and she was staying somewhere in the opposite of where I lived (and I mean like it was a 45 minutes drive home), and she would get upset with me when I didn't come visit her that often while she was here. She just acted incredibly melodramatic, accusing doctors of being racist because they didn't want to do what she wanted (I don't know if in the States, doctors just do what the patients want but that doesn't happen here). She wanted to get someone fired for over-plucking her brows, she went on for DAYS over wanting to get this person fired... She asked me if I had wanted to go somewhere extremely fancy and I said no (that's really not my vibe and she knows it) and then she like threw in my face how she brought a $2 shampoo we can't get here for me. The kicker was she was complaining about she took someone she had just met like a month prior for an all expense paid holiday to Europe for two weeks, and then this "friend" stopped speaking to he as soon as they got back, but whenever she's here I end up paying for everything and it's not about what I could get from her, but I mean how can she moan and complain about that to me knowing other than the $2 shampoo, and I always pay for the restaurants and all that, that I'd want to hear about how she can spend thousands on others?

So I ghosted her after all that.

But I feel quite bad now....it's been a few years and I saw last week in my FB Spam folder she messaged me last year but I don't know... I don't have the energy for that sort of friendship.

Should I reach out, be honest with her, just make up some excuse, etc?
