Wow! You just described my EXACT situation!! Do we know each other???
I was in Hospice and Home Health for 1.5 years, and experienced the EXACT SAME THING!!!
I quit for the exact same reasons as you mention, but I found myself in a hell-job at a SNF, not an office.
Worst job I have ever worked in my entire life! On my second day of work, it was announced that the facility was being investigated by the state! I was told I was off orientation because they needed to cover the shifts. (Seriously!)
Just like you, I also called my old job back. The options were either resume the old job (with the unlimited hours and driving), or be per diem.
Long story short, I lasted 29 days at the SNF. I'm just glad I came out with my license intact.
Did I go back to HH? No. I left that job for a reason. It was a good job with good people, but my family suffered for it.
Since I have been home, my home is cleaner, my husband is happier, my son is doing better, and believe it or not, the bills are still getting paid because I am not spending money on gas, lunches, auto repairs, and I have time to cook meals and watch our pennies. Things that have been put off again and again are finally getting done, and that feels great!
I have been doing serious soul-searching as to what I REALLY want to do in my nursing career. In the meantime, I have actually found a little niche for myself in on-call work! Teaching, private care... Now that I don't have to juggle so much, I have time to job hunt for a job that will fit me and my life, and is a job I want to do and can do.
So my advice to you? If you absolutely dread going into work and feel you are in a wrong place, chances are you are! Contrary to what people will tell you, there is no dishonor in quitting a job, and more jobs are out there. (Trust me, hell-jobs will always have openings!)
Your odds of finding a really good job are better if you aren't desperate to get out of a bad one. And if you want to go back into Hospice, at least you will know what you are getting into again.
Just my 2 cents...
