Can someone help calculate my possible BAC level during this blackout?

I wanna preface, I am an absolute idiot and I am not proud of the way Ive acted and Im staying sober. I am also an idiot of being not very educated on alcohol or BAC so please refrain from making fun of me.

I got extremely black out drunk in February. I don’t remember leaving the bar but I do remember the drinks I had up until I hit black out. I didnt eat at all this day until I had a burger with my first drink which was a Whiteclaw. I had another Whiteclaw shortly after. I then had a shot of Jägermeister. Then the bartender made me a Henny & Coke except it was the last of the bottle so she gave me the rest of it. I kid you not this glass was probably 80-90% Hennessy and 10% Coca Cola. I think I might have done another shot of Jäger after this but Im not entirely sure.

I made more than a complete mess of myself that night and acted in ways I never have before. I did end up in the hospital but it was because I had hurt myself and required stitches. I dont think or know if they even test your BAC at hospitals so I assume that wasnt done on me. I was told I didnt receive an IV either because they apparently thought I didnt need one. My partner unfortunately had to witness me in this state and said it was like I wasnt even me. They said that it seemed like I completely forgot who they were (we’ve been together for 3 years) and I was screaming that they were my abuser names and I was getting aggressive to them and myself (hence the stitches). I wasnt vomiting but I was told I was struggling to walk or speak coherently. I have no memory of any of this. I don’t remember getting home from the bar and I have a tiny flash of memory of the hospital.

I understand that I have a problem with my relationship with alcohol. Not here asking for advice on that, my question is how high was my blood alcohol level for me to reach such a stage of blackout and confusion but not be treated for it at the hospital? I was let go after the stitches were done. I am 21 Female, 5’6 and around 120 pounds. Ive been sober ever since this night, I never want to be that person again.
