Was my old boss jealous of me??

I've just always wondered but needed another's opinion.

When I first started my newest job, there was a young female manager there. She seemed okay at first but never came across as polite. My job involves doing 12 tasks (a lot of responsibility for a minimum wage/ part time job).

On the 3rd day working there, she pulled me into the backroom and asked me why I was there. I honestly did not know as it was my 3rd day and I was completely new and learning paperwork/computer programs. She told me she didn't like how I didn't click one of the right buttons on the computer programs and that because I didn't click it, it didn't show up on the paperwork. I apologized and she said she handled it the same day but was just frustrated.

On the 5th day working there, she calls me back again. She tells me I am disrespecting her because I didn't finish one of the jobs she told me to do. She basically told me to do a job that would take one hour and I was given two more jobs to do from the head boss, along with my other responsibilities. I could only manage 1/4 that and at the time, I made her aware that I would try my best but that the other manager gave me lots to do. So here I was and she's lecturing me about how to respect her and that she had to have another coworker do it (a coworker with only 2 responsibilities) and that they did it perfectly well.Then she invites another manager into the room (he's an older man that is a bit senile, no offense, it happens) and she tells me I'm disrespecting her and that I am not doing what she says and he literally just nods his head and says "mhm" three times, tells me to start working as I've been there two weeks (when it was my 5th day) and then leaves.

Then, after that, from then on, she was a total B to me. I started getting used to the system but there was a slight bend on one of the photocopies and she told me that I should never do that, ever. I should make sure they are all white without folds and gives me a serious talk.

Then she forgets to leave one of the daily task sheets on the desk, comes in the next day and asks why I didn't do it. I said I was on lunch, came back and it wasn't there. SHe said I was lying to her and that I should never ever give her an excuse. I said I was being honest and she just rolled her eyes and walked away.

Also, one day after coming back from lunch, she said she called me and didn't get a response. I said I was taking my lunch break and she told me to always make sure I am not fully on lunch. I wasn't even in the building though and when is that a rule that I can't eat lunch? I was away from my desk ,eating as I can't eat anywhere near my desk.

I was sick one day, was pale, was in and out of the bathroom throwing up and my coworkers are telling me to tell her I need to go home. I give in, tell her and she tells me no, I'm not allowed to leave. I tell her I'm sick and she said "do I look like I care? we need you here right now, you can't leave"

People started saying she might be jealous of me because she was obese, had no chin, lots of acne, really damaged hair, always dressed unprofessionally and had thick untamed eyebrows with a lisp and a weird jawline that stuck out...

What do you think? Sorry it's so long :(
