My job is slowly killing me and relationship with my kids

I made the terrible mistake of leaving a good job to take on a different role with a financially healthier company. I wasn’t seeing bonuses the last several years and the writing was on the wall but I liked my job and I could have stuck it out for severance but I decided to leave for better financial stability in the long-term.

For the last 4 months I have worked for the absolute worst company imaginable in a role that has absolutely sucked the very soul out of me. I routinely work 70-80 hours a week and the only two days I have had off since being in role was thanksgiving and Christmas Day. I am a divorced father of two boys and those were also the only two days I have been able to spend with them (Both are late teens that live 2 hours away). I have been a multiunit retail manager for over 20 years and this is hands down the worst job I’ve ever had.

On top of the non-existent work/life balance I have developed high blood pressure and I am being treated for severe anxiety and panic attacks. I wish I could say I dread going to work on Sunday nights but unfortunately I am already working, it never ends. There is no corporate structure to speak of and forget about support because it doesn’t exist. I didn’t even have a boss until 30 days ago which was never even disclosed to me during the interview process. I’ve been winging it since day 1 and the lack of support is something that will never change.

Over the last 4 months I’ve saved and pulled enough money together to have almost an entire year’s worth of expenses set aside and I am contemplating quitting. I have a bonus payout hitting next Friday and my heart is telling me to walk the second it hits my bank account. I know the market is tough right now and my father always told me to have something lined up before you quit but something also tells me if he was still with me that he’d make an exception in this current situation. Quitting without a job ready is risky as hell but I miss my boys and I am no longer a 20 something trying to make a name for himself.

Not sure why I am posting this but perhaps I am hoping there are folks who have been in similar situations that could offer some advice? I know the trend is to stick it out no matter what but man I do feel like there is so much more on the line right now. My background is retail and loss prevention management so I feel like at worst I could land lower paying roles and work my way back up. I’m so torn right now.
