Persecuted By Angry Female Manager

The lab manager thought I was doing something wrong and said "I need to talk to you outside", she walks me outside to the hallway where upon she turns flaming red in the face and yells at me for 5 minutes about how she "knew" something like this would happen and how I would mess up and how she "must" tell our boss about this incident. I defend myself but she doesn't hear it. Anyway, I go back in the lab and my eyes start watering and all of my coworkers are like what the hell just happened out there. My mentor tries to help me with my experiment and I can't even talk or look anyone in the eye. I just keep looking down and away from the friggin traumatic incident of getting yelled at by a flaming red 32 year old female who I don't know very well. I go downstairs to work and find my manager and lab tech talking and she apologizes to me for the misunderstanding and said she didn't mean to yell. Oh gee, why didn't you figure out the facts BEFORE you yelled at your employees.

I start doing my work in a room downstairs that is usually empty and I bawllllllllllllll my eyes out. About 10 minutes into my bawling 3 of my coworkers come "visit" me and console me. I'm still bawling like a big fat baby. It was the first time I got yelled at by someone that's not my family. I was explaining to them what happened and they just listened with watery eyes too bc they'd never seen me cry or be sad. It was a sad movie and most of my coworkers are softies. Then my mentor comes to visit me and I try my hardest NOT to cry because I want to seem like i'm not a child but my eyes are watery and red and I tell him everything and he gets teary eyed bc I started to cry. Then, the lab tech was crying too and wanted to quit bc he thought he got me in trouble (when he didn't).

Basically, the crazy lab manager made an impulsive decision based on her having it out for me (for 2 years) and made everyone sad. Being sad is not productive.
