what's the best move

So I personally have about 2.5 years of experience. About 1 for subacute (rehab\LTAC) and 1.5 for med surg. Recently I was offered a position on a PCU at different hospital. I jumped at the opportunity as I wanted critical care experience. At my then current place of employment I had dropped down to a registry position as I had taken on the responsibility of care for my mother doing home hemodialysis and other care. I approached my boss and asked her if I could have the opportunity to select what days i work(as my boss and I had previously agreed on every Friday even though my written contract was one day a pay period) to accommodate my orientation. She seemed disappointed that I was not coming back full time and said she would get back to me. Well orientation was coming so I called in 2 Fridays. My boss avoided getting back to me and I didn't want to lose out on the opportunity so I resigned instead of continuously calling in. After being at the new place for some time I found it very dissatisfing. The nurses wanted to gossip instead of orientating me or just left me on my own since I was not a"new grad ". Acuity was not taken into consideration with assignments. And it was a revolving door for patients. They push unstable patients to the floor just to get admissions in and the next there is a RR or code blue. One of my preceptor cried because the patient we sent died. The ratio is 3:1 but one nurse gets like 4 admissions a shift which is crazy. And then once you've completed the admission the want you to give the patient to another and take a new admit. I've approached the director with my concerns and she just states the staff complains too much, she'll look in to it and wants me as her spokes woman. I called my previous job that I resigned from and asked if they still needed help. They said yeah and would get back to me after talking to HR. I don't want to look like an idiot begging for old job back but I don't want to work somewhere I don't feel comfortable or have a reliable resource. Should I just wait it out until it gets better or return back to my old job.
