Quit my job

So I’m 18 and pregnant, just moved back with my mom (due to my boyfriend and I breaking up he was cheating and manipulating) and got a new job a week ago. I was so excited. It’s a Korean BBQ place and I was a server. I felt like I was doing really good, but the owner is so mean to me. She would yell at me everyday and I would try and just agree with her and apologize but she finds anything and everything to yell at me about. I understand that I mess up on somethings but I felt like I was doing good and of course I’m not gonna be as fast as everyone else because I’ve been a server for less then a week. She literally called me slow and dumb. But I really tried my hardest and now I’m just so sad I feel like I’m failing my daughter I know it’s not a big deal it’s just a job and I can get another but I feel like such a piece of shit I just wanna do my best and I couldn’t even do a waitressing job right 😭😭 When I quit I just started crying and clocked out and left and didn’t say anything... should I text her or leave it

- another thing they hired another girl that was like 27 and has been waitressing for like 7 years and she kept comparing me to her, this other girl was hired after me... maybe she was trying to bullying me into quitting.

Should I text her this or something else? This is pretty emotional but that’s how I feel lol. Pretty unprofessional but idk what else to say she’s made me wanna cry everyday that I’ve worked there literally less then a week
