Unfortunately I feel sorry for many famous people in this regard - they are surrounded by people who have little interest in their mental health. The type of spot light put on these people, treating their lives like some sort of zoo or freak show is never going to do them any good.
Look at Amy Winehouse constantly taken out of restaurant front doors, completely wasted (often by her own father) rather than discretely carries out through the kitchens.
Unfortunately the type of people attracted to fame these days (and it is often the fame and fortune they are attracted to rather than the need to create/perform etc) are often precisely the type of people easily manipulated by others and least able to cope with the consequences. What we are often seeing with famous people is a facade, a persona facing the world for the usually material benefit of others. The facade is disposable, it doesn’t matter if these people fall off their pedestal into the fiery pits of media hell. No one is going to save the likes of Kanye, to many the more of a freak show he presents the better, because this is what many now see as entertainment, something to fuel the gossip pages.
People think watching The Kardashians, Love Island - all “reality“ TV is harmless fun, but the culture it has created, with expectations so far removed from reality has created a lot of harm both for individuals and society.
So no, no one will help Kanye, because the people who have the power to do this have no incentive to (except maybe to keep their puppet alive, allowing him to walk up to the edge of the Cliff and spectacularly pulling him back at the last minute).
