Does this mean I should quit?

I feel undervalued at work. I am a receptionist and I am the lead receptionist and do all the work. Most of the time I’m just sitting there but any important task is given to me. For the past week my boss ( the woman who hired me hasn’t been there and it’s very hard to get in touch with her. She was in a car accident a couple of weeks ago and was sore but not enough to where she couldn’t function. I’ve been kept in the dark about her not showing up and have no idea when she’s coming back.

It’s only frustrating for me because people ask me for her and I don’t know what to tell them.
There is an event this weekend which is a brunch where over 60 people have rsvpd and I was in charge of calling most of the people personally and trying to confirm with them. I was also in charge of putting together gift boxes for the event. I’m kept in the dark about a lot of stuff and didn’t know what time or anything about the event until some of the guests told me.

There is a weekend concierge who I assumed would be the only one working but they also asked the other concierge who comes in after me and is part time to be there. She is a pretty white girl. The executive director shows favoritism to her and will tell her how pretty she is and will do whatever she can to talk to her. I’m also pretty and have been told many times ( not by these people though ) but I’m full time and they didn’t invite me to come help out the day of the event.

The event is basically a sales brunch to try and get people to move in. I kind of assumed because maybe it was because I’m full time and didn’t have enough hours but it did hurt me a little because I wasn’t even invited to help with something that I helped put together. Is this a red flag?
