(inspired by an illness mentioned in the Bloodline novel: http://starwars.wikia.com/wiki/Bloodburn, mild spoilers for the book)
When his mother died Poe was too young to understand why - only that she'd gotten increasingly weak, was often bedridden and finally died the summer Poe was spending time with Kes' family off-world. Later Poe learned Shara had bloodburn and it finally caught up with her, ironically just as she'd settled into a quiet, stress-free life.
Much later, after running a series of difficult missions for the Resistance, Poe starts feeling sick. He learns that while he doesn't have bloodburn like his mother did, he's very likely to develop it soon if he doesn't make some changes, like fly a lot less, reduce stress, maybe take some medication. On the one hand Poe really hates the idea of being grounded even for a short while and feeling useless because of that, but on the other hand now that he has his life together and he has Finn and doing something that matters, he realizes he's really scared of dying. So: Poe trying to figure out what the next step is, with Finn and all this friends being supportive and caring.
