The REAL reason she was dying was because they had no more Carrie Fisher footage and they had to do something to force her death and this was their choice. I always assumed the strength she took to reach out to him and interrupt him mid-fight was beyond her normal capabilities. May have been that she helped in the healing as well on top of that, but either way it feels forced. At some point the light side of the force, his death, and Leia together were able to bring him back to the light side. The talk with Han was the representation of him coming back.

She got shot into space, dude. That’ll do a number on the ol’ internals, no matter how force-y you are. Her days were numbered.

The other two carked it in the two previous films, it seemed inevitable that she would in this one, too.
