I think the main problem here is not being alone itself, it's the betrayal, putting others first, maybe expecting that the people she helped will pay her back in return not necessarily financially but being there for her when she's old. She invested on them, and it was a really bad one... That kind of betrayal will put me into depression too, just constantly blaming myself for the wrong decisions I've made when I was younger.
But yeah, we all need friends and support systems. I believe others can live alone and be fine with it because some people really can or thrive when they're alone but we all need to have someone to talk to every now and then. A lesson for us younger people. 😓
The happy ending I personally want for her is no longer feasible the moment she came back from overseas. She could've chosen to live the rest of her days with her employer and they were absolutely fine taking care of her after all those 39 years of remaining with the family, that's like 2 to 3 generations worth of loyalty but she opted to live in the Philippines for retirement, in a way, she had pride as a worker that she knew her body wouldn't be able to handle the daily chores anymore and despite having that safety net, she opted not go back and this is her ending. Bad things happen to good people and even more so to people that don't even deserve it.
Blood is thicker than water but she forgot water was there for her for most of the time. And blood didn't care.
One of the disadvantages of our culture having strong familial ties. Sad for her. :/
