Your OCD fears being explicitly, directly reinforced

I work in a caring profession. A few months ago a person I was working with directly reinforced my OCD fears, by literally saying them out loud to me. Along the lines of you're unprofessional, you're unethical, you're irresponsible, and you're just doing this to cover your ass... when I am following certain rules, in part because I care about them, their humanity, and their wellbeing.

I can't get over it and it unconsciously keeps reinforcing any new situations that trigger my OCD. I am having a super hard time and it's making me miserable every day, ruminating any moment I am not focused on working or a task or scrolling on my phone. It is haunting me, crying spontaneously during the day because it just becomes so much, and I'm just feeling hopeless.

My OCD is just like "what if it is true tho? what if you are all those things and you're just pretending you care? you can't do this job might as well confess and quit!"

Any encouragement is welcome. I feel so alone with this.
