Exit interview request - yes/no

Recently left a management position - abruptly. Still feels like I should have more closure. What should I do ? Went into work in am my manager blasts out in a rush says she rearranged my teams responsibilities for the day putting my top productive person to a menial task for an entry level - during a time of high call volume and need to catch up with many unhappy consumers needing call backs as well I voiced my dislike and the direction corporate wants the team to be managed - she blew up in front of team and consumers - requested privacy and she was like why??? Went into private area during the conversation which she was yelling and acting off the wall - she lurched at me yelling then stomped off and out! In shock I chose to leave right then - shaking and shocked. NEver seen such behavior in a work place! I texted and left message for my Corp lead of the situation and texted my team at night I could not work under this type of behavior or management style and appreciated all they have done during my time there After a period of trying to analyze wth happened the next day I texted manager and she said you quit I made plans already - thus ??? What would you suggest I should do. Never sent resignation to Corp HR. Sure she set the picture differently when explaining what happened My nerves and stress level are now at normal level again after working some weeks 7 days non stop 9am to sometimes midnight!!! Loss my comp time and never signed a contract for salary but changed to it at Mgr verbal request. How should I put closure - never asked to do an exit interview or anything. Hostile toxic work environment in ? Salary left me working for less than min wage - working all these hours consistently. Should I reach out to HR at all or chock it up to a bad experience and leave it alone. Btw this was not a career position - came out of retirement to help organize and create remote team prior to business opening for summer season. All fine then until we hit the ground at the worksite!
