Should I have quit?

I am a nursing student who recently acquired and quit a resident assistant position at a. assisted living facility. I really liked my job, so I have been mulling over my decision to quit for months. I honestly don't believe it would have worked out and I know it was not a good fit, but that still does not stop me from feeling like a quitter. I felt like the job was simply asking far too much far too soon.

Here are the combined reasons I quit, tell me if you think it was justified:

-They texted me everyday, any time of the day, and multiple times a day, about things that were not at all urgent. I felt like I was never off work.

-They also published my personal phone number in the employee lounge without notice or my consent.

-I got hired and paid as a part time employee. My schedule for my first week out of training had over 45 hours on it. No benefits and no days off.

-My first week out of training they also expected me to clean and take care of a building of 50 residents by myself, which would have been 2x more duties and residents than anyone else on the same shift.

-They scheduled me to work morning, evening, and night shifts all in the same week (and loved calling me the morning after a night shift)

-They didn't pay me shift the differential

-They were also trying to get me to sign some contract saying that I was personally responsible if anything happened to their new ipads. I was apparently suppose to store the ipads on a cleaning cart in the hall and still be personally responsible for theft and damage.

I felt like this job was trying to take over my life and I was not willing to sell it for 10 dollars an hour. I guess what I am truly seeking to know is if others would have endured it and for how long. I did not want to give up my 4.0 nursing gpa, but working mornings, evenings, and nights was making me too tired to concentrate on my studies. I quit the second week and did not give 2 week notice. I really liked being a resident assistant, but with all the issues with management I feared no amount of talking would have made this a good fit for me.
