The problem is that in our society we put the notion of celebrity on such a pedestal that we think of it almost like attaining godhood. There are a few actors who do achieve massive stardom and become something close to gods in our world... but that is a very small percentage. For the vast majority of actors, acting is just a job. A grind no different from driving a city bus... except that the bus driver has health insurance, pension, benefits and doesn't have a manager and an agent taking like 15% of their check, plus a nutritionist, a stylist, a physical trainer, dealing with sexual harassment and exploitation as a normal part of work, etc.
Very few actors are able to survive solely on their acting work, including actors you frequently see on tv. Remember that time everybody made this big deal about Elvin from the Cosby Show getting caught working at Whole Foods? Look at his IMDB page... it's not like he gave up acting. He's working pretty regularly on tv and yet he still gotta grab a side gig to make ends meet.
This lady wasn't on the main cast of "Friends" or "Seinfeld"... She was a recurring character on a black sitcom on UPN. IMDB says she did 13 episodes of The Parkers. I really doubt she was rolling in the dough. For actors on that level, it's really feast and famine. You might get a job on a few episodes of a sitcom and make $50k... and then you don't work again for a year and a half. Like, you'd be surprised how many actors would absolutely love to get a good job in a hospital where you got some kind of stability.
So I say... don't cry for her, Argentina. I'm sure she's fine. And she seems to be happy.
