Overworked Tony begging for rest

[cross-hatched.livejournal.com]

Hello! I have a very specific story I remember reading and cannot for the life of me find again! I remember it was an overworked Tony, who was at a breaking point. It was bad enough that when he got struck down in battle (with things coming through a portal I believe) and Steve comes to check on him, he thinks Steve wants him to keep fighting. He ends up begging Steve not to make him fight anymore, to let him rest.

If that rings any bells, I'd really like to reread the piece! Also, if anyone has some general overworked/under appreciated Tony fics they want to pass along, I'm always looking for more!

Thank you!
