Work injury

Hey I injured my back at work and I had the smartest ideal to not go to the hospital until 3 days later when I still felt pain the urgent care Dr put my on light duty but i suffer from bpd n panic attacks and it’s really stressful coming into work everyday the dr said my job needs to call them to have my note revised but it’s been a month and they won’t call idk what to do so I decided to tell HR that i have those disorders & now he wants to sit with me n the job nurse to talk about it i usually work 12hrs but since the accident I work 8 and even that’s too much with a back injury
