Looking For Castiel PTSD fan fic
I would have read it on ao3 recently. I’m pretty sure it’s multiple chapters, and it’s definitely illustrated. In the fanfic Cas has PTSD and is scared of water. It’s set in the shows canon, not an au or anything. There’s a picture of him crouching and crying in a shower. I remember that he goes to get Sam food, but it’s raining and he gets trapped outside. It might be destiel, but that’s not the main focus. Thank you!
