<human>: Can you provide a brief rundown of the text in within 3 sentences?

Preface:
I left my job about five months ago due to harassment by my old boss. I worked as a preschool teacher for about a year and seven months before leaving, I started as an assistant and eventually got my own room as a lead teacher in the daycare.

She would ignore me (when I had issues or problems with parents or children), kicked me out of my classroom, spoke negatively about me and picked on me about any little issue parents had. Before this, I was the "best teacher" in her eyes and would swoon over everything I did which was weird cause I was doing what my job description was...I was flexible with my time and adaptable without bitching.

My boyfriend got reconstructive surgery on his ankle which required lots of help from me; we couldn't hire a helper (we live far so no friends near by) so I told my director and assistant director ahead of time (two months before surgery date) I needed a part-time schedule to help my drugged up bf for a bit. So, they ignored my request and made my life a hell after I brought up my request. I quit after being very emotionally distraught when a lot of stuff happened, usually I don't care but I loved the kids in my classroom and it affected my work ethic..oops. I left abruptly one day when I was close to breaking down..the dumbest move I've ever made in my job history.

Anyway, I've been applying to other places and am wondering if I should even bring up this issue? Applications ask what was the reason for leaving, I'm not sure what to put? I say no to contacting my old boss since she has retired this month. I think I lost a potential job when I explained what happened and "yes" to contacting my references.
<bot>: I quit my job for bs reasons and now looking for new jobs, should I tell them upfront what happened or not? what do?! :(
