I looooove the manga I can't even breathe without you and how the seme takes care of the uke. This is an extreme case of this type of thing, but I'm looking for things where one needs to be taken care of, wether its because of health, money, or plain "I fail at life." Suggestions?

Aiso Tsukashi. It is quite different from the one you mentioned though, it has a darker atmosphere, more smut-ish, only three chapters and is on going. One of my favorites.

Wow this is hard! Lemme give this a try. Granted, some may not fit your request, but hopefully you'll enjoy them all the same.

Bannin 1st Story (Be warned that this is quite the unhappy story, to say the least)
Natsujikan 5th Story: The Sleeping Man
Ai no Kotoba wo Uragaeshi 1st and 2nd Chapters
Katsubou no Manazashi
Kanga Na Spoon
Taiyou no Shita de Warae

Name of Love and Make Me Happy, stories 5-6, both by MIYAMOTO Kano
Uso to Kiss
Hachimitsu Darling
Hidoi Otoko (AOI Akira)
Wild Rock, maybe
Hohoemi no Nichijou, 1st story

Hope some of these are what you're looking for.

Love Mode - Naoya's apartment is burned down, Reiji takes him in.

Punch Up - When Kouta got into an accident and lost his memory.
The Summit
Twin's Labyrinth
Under Grand Hotel - Rather than one taking care of the other, it's more like one protecting the other.
