Should I Quit?

not sure if this is the right place to put this but im not active enough in reddit to use the mcdonalds employees sub 😭

i've been working at mcdonalds since early september, and i've hated EVERY moment of it. the work is either boring, stressful, or overwhelming, and i dint think any of my managers really like me. they all send me to the back window for every shift and the only interaction i get with people are the customers or the brief conversation with one specific guy in kitchen.
i dont really need the income as im a minor that cant drive yet, and thats another problem. getting rides to work is becoming tougher as my parents work weekdays and my brother occasionally works too. the customers frequently get in my nerves, theres no stool in the back so i stand the entire shift (minus my 30 min break that is usually like 2 hours into my 8 hour shift), and the uniform is so uncomfortable it makes me want to cry. right now my biggest question is can j wuit on the spot or should i put in my two weeks notice? i have a short shift tomorrow (at a location i have never worked at, another reason i really want to quit) and i frankly dont want to go.
another reason is that i am doing summer school this summer, so i need weekdays open. but my parents work on weekdays, and on weekends i cant work as ill have no ride due to them not being home, or i will also not be home. summer is usually very busy for me, and dealing with work and school at the same time was also very challenging.
thinking about work also makes me want to cry so if even just for the sake of my mental health, quitting is probably the best option for me, i just dont know when or how.
advice would be GREATLY appreciated 🥹🙏
