How to keep distance from patients in psychiatry as a student with pre-existing conditions?

Hello. I'm a 5th year medical student currently on psychiatry rotation for 6 weeks. For context, I've been diagnosed and medicated for the past 4 year for depression, anxiety, and dpdr. As you may already know, dpdr episodes can make you feel like you're "going crazy" (I hate that word). That's why when I saw my first schizophrenic patient who was off his meds and who was so smart and good with words, it messed with my head that's already fragile with dpdr and I had this surge of anxiety but couldn't leave the room as the doctor wasn't done with the interview. Do you have any tips on how to distance myself from the patients? I think the fact that I relate to their struggles is good to an extent, but when it's too much it becomes detrimental to us both. Part of me wants to present a letter from my psychiatrist who's also a professor in the ward and just not do this rotation but I won't learn that way and will always be scared of psychiatric patients. What do you think?
