WIBTAH for wanting to work alone after working with my friend and promising i’d do work with her ?

i (17f) have this project which is really important for my overall grade of the course and initially i was going to work by myself but my friend (20f) said i should work with her for the project because she’s already done said project before in her old course and she kept saying i needed to do more work so i don’t go down the same path that she does, so because shes done the project before i decided to work with her (to be honest it felt like i didn’t have a choice at the time) and i honestly should’ve said no in the beginning but i decided to because she “wanted the best for me”, she says she has an idea and the teacher said it was a good one too, i just agree with her and what she wants to do because it did sound fun im not gonna lie, but the reason why i wanna work alone is because a few weeks into the project it went from something that was supposed to be fun to something that felt forced, e.g she would take my phone and make me work (sometimes she would just snatch it or shout at me for being on the phone) the one time i wasn’t in she called me over 10 times and spoke about how i need to be in every day and on time for the project, and i started to look at what everyone else was doing for the project and it was actually their own ideas, like she would help this other girl with her ideas and act like she knows everything and then after they finish speaking she would tell me to get back to work like im some type of servant helping her ..

my other friend (18f) even told me about some assignments i’ve missed because i’ve been solely only working on this project because of how she would tell me this is the most important, i was even able to speak to my other friend way more yesterday because she wasn’t in and do more activities with other people

other people’s ideas were more carefree about it and i realised it was genuinely not as serious as she made it and it was supposed to be something I ACTUALLY WANTED TO DO and not something i had to do because “the teacher said it was good”, yesterday i spoke to the teacher and showed him what my initial idea was, he actually said it was really good and my other friend (18f) explained to my teacher that she’s basically making me do her project, but the thing is ik she just wants me to pass and if i say i wanna do the project alone she’s genuinely gonna get so mad at me (she gets mad really easily) and i did say in the beginning that id work with her but the more i think about everything the more i realise i just did that because she would always say she knew what she was doing (bc obviously she’s done the project before), but i don’t really wanna make her upset because ik she also wants to work with me because “she sees my talent” and bc her idea is pretty good, but i really wanna do my own idea.. my other friend did say that i should definitely do it on my own because she knew that i initially wanted to do something else and felt a bit off when i suddenly completely changed my mind.
