Help a SISTER OUT (ITS LONG) 😅

I need some advice or what ever but don’t be rude but honest 😅

okay so you guys I been working at this warehouse job for about roughly 1 year and my last relationship was three years ago -it was toxic-!!! (he had a baby on me)okay so boom I cut him off and told them wish them the best okay so boom fast forward to now !! I recently just found out (his baby mama) is working at my job ( I knew what she look like due to her working at my old job previously! That how I found out he was cheating && etc ) I quit && found another warehouse job due to the embarrassment && so on!!! Well recently like I said before I found out she works for security (they’re contacted thru another company) but still !!! when I walked passed I get a hard stare !!! Okay booom I think nothing of it but recently it’s been happening a lot lately (the stares) the laughing loud etc(they have a desk area by the break room)

Okay so this is where I need your opinions not only did she tell me she would spit on me but also told me my nose was to big so that makes me ugly && with all that I wanted to know WHY DOES SHE STARE or yet why does she make herself known that she there (for example you guys she did a ballerina turn and stopped in my direction I was so confused ! She literally did a turn as shown in the gif!

So guys why am I experiencing the hard stares !! && before u say ohh are you loook her direction !!!… nope I would be having conversations with people (while on break or so on) && I would see something staring or looking in the corner of my eye && when I look up it’s her as if she hasn’t seen me before !! it’s getting weird ! PLEASE HELP A SISTER OUT !!
