help me/what should I do ?

recently got a job at my parents family friends restaurant. only been scheduled 6 hours in total since being hired last month, worked 2 days total 3 hours each day. 

first day was training automatically the girl training me is nitpicking everything I’m doing expecting me to know everything already as if it’s not MY FIRST DAY. “Don’t scoop the rice that way do it like this” (I live in an Asian house hold I think I know how to do something like scooping rice…) she constantly makes me redo stuff the same exact way I had just done it because I apparently wasn’t “doing it right”?

once clocked out I say bye to her and she ignores me. Later on in the day the manager (my parents friend) text me that the girl who trained said “you were really slow and need to speak up customer service is important to me…” weird and unnecessary and she didn’t tell me one good thing I did(keep in mind I was only asked to repeat myself 1 time the 3 hours I was there because I stuttered over my words) so I of course stand up for myself and say ”it’s my first day it’s going to take me time to learn everything since it’s all new to me“ 

she says “well I was just telling you!” 

next day I’m scheduled and 1 hour before my shift starts she messages me telling me I don’t have to go in cause it’s “slow” (I’m upset bc I just got out the shower and already had my work clothes on) 

she then tells me to come in next week Sunday & Saturday instead so Thursday rolls around and she texts me not to go in Saturday then friday(technically Saturday morning) she says to come in and Saturday at 10am she tells me nvm not to go in. (I don’t respond because of course I’m annoyed she keeps changing her mind and on top of that my moms in the hospital barley getting done with her surgery and I’m there taking care of her) 

I ask her if I still go in Sunday instead and she’s upset saying “what got something to do?I texted you and you didn’t respond why” I tell her “my moms in the hospital I’ve been here since 4am it is now 5pm and I’m running off no sleep I’ve been busy today” she ignored the message and says “yes you work 12pm get off at 2 if slow and 2:30 if busy” 

I go in (straight from the hospital) and i honestly feel like I gotten the hang of everything I’m moving pretty quick (even doing things without being told to do them) the girl who trained me last time as I’m talking to a customer tells me “speak up you’re taking to low the customer can’t hear you”  funny thing is the customer speaks up and says “I actually can hear her fine” 

fast forward a whole week goes by and I’m not scheduled, she never told me where my schedule will be put up nor how I would get paid? 

so I text her and she tells me “I can’t schedule you this week I’m throwing a celebration party for(girl who trained me)” (all these people are family of course she is) she also goes to say “I’m not scheduling you more hours because you’re still slow” (how tf am I supposed to pick up the pace when I’ve only worked 2 FUCKING DAYS TOTAL?!? And I’m either not getting scheduled or getting taken off the schedule)

another week goes by and she text me today out of the blue “you work Saturday/Sunday 12” “text me ur social and drivers license”

I end up losing track of time and was busy as I’ve had 3 interviews today for 3 different jobs (I’m actively searching for something else to get out of there) so I take a bit to respond since I’m not on my phone she just texted me rn saying “do you not work for me no more? It doesn’t take 5 hours to respond to me” 

I’m fed up already what do you think I should do? or if you were in my situation what would you do? (I do wanna quit but I’m unsure what to respond to her with since I’ve never quit let alone been spoken to this way..)

(I also went home crying the first day cause of how rude my trainer was being slamming things and rolling her eyes at me acting like I was a burden to her)

also repost (I left out some details and fixed my words)
