I had to search for a two week long intership for 10th grade, i literally started asking jobs the same day i found out. (i'm disabled (autism), which isnt that much of a deal but my teacher told me that i should mention it just in case) which led me to rejection almost everywhere. so, as a last resort someone i know recommended me this small café. i introduced myself, said that i struggle with talking to strangers and that i'd rather be in the kitchen/behind the counter etc. she said it's no problem at all and that i'd be fine. so i start there and i literally get left alone and she lets me handle everything?? i had no idea how anything works and guests kept coming up asking all kinds of stuff to pay/order or whatever but obviously i had no idea what to do so i went to get my boss and she told me not to bother her and just deal with it.. so fastforward i literally did whatever felt right and made lots of mistakes. during the week she kept asking super weird and personal questions that i dont think were normal? such as "what exactly is wrong with you? i mean, other people ur age dont act like this." "what did your parents do to you" "have you thought of going to a mental hospital" i didnt know how to appropriately answer so i just shrugged which also upset her. and then the last straw for her was, when i was super overstimulated due to everything going on, and having to do customer service again which i was promised i didnt have to do, i sat down for a second and had to take a breather. she completely lost it. she started yelling at me that im good for nothing and so much horrible more things, i began to cry which i did try to hide but did not work and made her even more aggressive. she randomly started talking about how she knows this other girl my age from afghanistan that doesnt even know if her parents are alive and how she can handle things better than me (mind you, im also a woc who lost family members due to war). she told me that shes not a caretaker and she doesnt have to deal with r*tards like me. she fired me that day lmao.

i have no idea if this is my fault. what should i have done instead?
