There's this thing people do where they get very, very concerned about their fave(s) either in their personal relationships or in their careers (or both) when something doesn't line up entirely with their perception of them. This can sometimes be legitimate, of course, but often there's a near-hysteric state of doom-ism that comes from spiralling down into a scenario where the fan, specifically, loses the stream of content and in turn the enjoyment and community, and sometimes the 'win' that comes from this continued content.

You see this a lot when actors suggest retirement or a show ending or someone just perceives them as having a not-great day. "I'm so worried, what are they doing, their friends/spouses are evil -" etc.

All entertainers are people. People with rich internal and private lives and they are allowed to retire early, or take projects they want vs what would net them the most publicity, or whatever else.

It's fine to feel sad about this when something ends, it's natural! But if you find yourself constantly thrown into these what-if spirals by any little thing you need to step back and examine how closely you're tying this perception of your faves to your own happiness - and if it's even making you happy at all anymore. Something you enjoy should not stress you out to the point of depression and tears.

Edit: TLDR Thesis statement here is I you need to take these trigger points, step back, and realise when something has stopped actually being about your fave and has turned into using them almost as an avatar for your own happiness.
