I just started a job in a mental health clinic and I feel like my coworkers lack empathy towards the patients

They literally make fun of them all the time and this is a clinic for TMS and ketamine therapy, so for people with severe depression and OCD. I actually said to them today (my third day training) “wow yall are mean as fuck to your patients” and maybe I shouldn’t have said that, I’m sure they don’t like me anymore, but as someone who has actually experienced severe depression the thought that people who are supposed to be caring for me would laugh about me and belittle me behind my back like that is sickening. I feel alone in this but maybe it’s just part of the job to become callous like that. Idk man it’s sad
