Should I quit my toxic warehouse job to study sonography full time?

I’m 28.
I’ve been at a clothing warehouse for 4 years. I should of been promoted by now, & past months tried my best be trainer / lead & asked supervisors & did tests but it seems they only choose friends & this year job became less professional & like high school. Only mean girls r being promoted happy to see me stuck as regular worker failing. I always been told im a good worker & new hires ask me for help daily. I’m being denied change to day shift due to school. While others are easily changed to their part time flex schedules.

I want go to school full time to be sonographer , do ultrasounds 2 years need go to school.
but I would need part time job to pay for food gas & my bills & rent a cheap studio room.
I want start sep.

most not point waste time as full time worker forver night shift if I’m being treated like trash.

I also wanted try get new job as lead/ trainer full time as pay would be higher like $23/24 an hour. However even tho I have strong desire lead be part of leadership , I want have degree so my future is secured. & want take break from people , coworkers & study at home focus on school work in my peaceful sancuary.

the job I’m at is far from moms apt & I spend too much gas. I felt like home at this job but it’s my time to leave. No point stay 5 more years never promoted. I haven’t been able rent a studio over there as gas & bills were high.
