How to address traumatic OR experiences on resume without harm?

A little job search advice please

So I left the floor (MS/T) in 2024 to go into the OR, the first facility didn't work out due my supervisor creating an extremely hostile and toxic work environment.  My therapist believes  I now suffer from PSTD from that experience.  I held on for a year then went to a different facility in another state to start over in another OR.  

That situation failed spectacularly (not because of the environment the staff were extremely nice and very professional).  I realized that I just didn't have the tools to function well in the OR - I apparently had underlying severe ADHD triggered by the PTSD from the OR I started at? (IDK still unpacking that one with my therapist).  I worked at the second facility for 4 months, they gave me the option to be terminated or resign.  I resigned but the whole thing was super humiliating.  My dilemma: 

How do I put this on my resume? Do I put the second facility on my resume at all? If so, where do I get a reference from for that second facility? Do I keep the second facility off? If so, how do I account for the gap in employment for those months? 

I'm not going back into the OR (at least not until I can get my ADHD under control), but if I can help it I don't want to go back to the floor because patient ratios were killing me. 

Any advice on next steps would be greatly appreciated.  

I'm in the northeast NYC, NJ, PA, DE, MD area.
