pls let me know asap if i did the right thing!

at first management was very supportive to me yet after about 2 months, two of my managers have acting so two-faced with me and seem offended with me for no reason. i was only scheduled to work until next friday even though i have most days free , and my manager seems to dislike me and is slowly cutting my hours and days. i asked my manager to have that friday off, but i needed to see if my coworkers can cover my shift and then let my manager know so she can approve, yet no one could cover me?. i didnt know if i should haved stayed or left because i would like to have the job on my resume as experience, yet the environment was not the best anymore.i decided to send her a message that i am quitting and will not show up. i guess i am free but i feel bad bc my other coworkers my age were really nice to me and most of the customers were really sweet. idk if i did the right thing
