someone insulted my weight

i have never been effected by weight jokes and people calling me fat because i am and theres nothing wrong with that. I’ll lose the weight when i want, and as of right now im working on it. Ive always been more heavyset, but have never really been the punch line for jokes until today.

my shift lead at work has been constantly insulting me to my face and my coworkers, its annoying me but i put it off as her being a miserable 40 year old woman with no life since she’s basically bullying an 18 year old. but today she kept poking jokes at my weight, and going to my friend and talking shit. Saying i “take up two seats in her car” (which isn’t remotely true, lol) and other harsh remarks.

I tried not to let it bother me but im getting in my head about it, i feel so much more aware of my weight and the fact people might think about me like that. Its made me completely lose my appetite, and i want to go back into my old habits of ednos. I lost a ton of weight when my dad died because i was hardly eating, and then binged it all back and more. I just dont understand how people can say things like this, she doesnt even know me. I guess i just need support, how do i get past this? its truely bothering me and i cant just say its not a problem. I feel basically worthless. i just dont want to eat anymore.

edit: spelling mistakes and if like to point out a few things;

-I am not insulting her or making fun of her age, i couldnt care less if she’s 40. She could be 20 doing this and i would say she’s miserable and had no life, lol.

-i did not binge OR starve due to this! i am very proud of myself, and thought some would like to know. :) i stayed consistent with my calorie goal and my portion control which ive always had trouble with since my emotions effect my eating habits terribly.

-i have contacted my manager, my friend has given details and he will be talking to shift lead about this on Monday. if she continues to harass me and insult me i will go to hr and take all of your advice.

-lastly i am so grateful for the support. my friend was there for me but its comforting for people to have my back, especially since another shift lead said my friend shouldnt of told me since i said something to him about it.
