Jay always had difficulty breathing especially when everything got to much. He never told anyone at work it never happens at work unless he started to neglect his health when w case got to hard. Will has poked and prodded for him to tell Voight if he did happen at work—it has but everytime it didn't Jay found a supply closet and calmed down alone.

Kevin and Adam caught on only because they noticed his anxious behaviors. They promised not to tell as long as it didn't do intrude on his work.

A case is getting too much, Jay hasn't been sleeping enough or eating enough and its been affecting him. Eventually his chest started to tighten up and he felt the panic rise like normal and so he walked—ran to a supply closet slamming the door and sliding down it. His legs knocking into the brooms.
