I purposely ignored the children at my job

I’m a deaf girl that works as a teaching assistant in a year 1 class room it’s very loud and honestly overwhelming I struggle a lot at my current placement I’m moving after half term for work I have to use my cochlear implant I don’t get a choice I’m required too but it’s really hard especially with children crying or screaming my brain struggle’s especially since my current position is to work with 1 to 1 with an autistic boy so if he becomes too out of control for me I literally leave to the bathroom take off my cochlear device and sometimes cry honestly the noise in the classroom is horrible enough for people who normally hear everything but especially for me who usually don’t hear to becomes a lot for me like overwhelming

And if anyone found out before I resigned I would’ve been fired and even now I’m leaving I feel bad for leaving an autistic child I can’t deal with with the class teacher and even leaving the entire class because I know it’s overwhelming for others yet I can just leave so I just feel guilty
