My last job screwed me over when it came to my disability, and I’m scared to disclose it to the next one- but I need accommodation. Any advice?

I just need notification if a certain person is on campus. Most places, almost never have this person there anyways. The second my last employer found out, they weaponized it against me. Literally sending that person to my home, locking Me in rooms with that person, even mocking my request. When HR tried to help, they terminated HR and made my life a living hell. I’ll probably be in news for it and am scared about how my new employer might handle that too. I can’t express how scared I am.
