quitting my job?

Hey everyone, I need some advice/words of encouragement.

I am totally over my job. I currently work at a pretty large teaching hospital that’s apart of a large healthcare network on a telemetry unit, and I am so burnt out. I started last July 13th, so I only have a few weeks till I start my year, but I want to put in a 4 week notice and just quit. I’ve decided bedside isn’t for me and I have been looking/applying to random jobs I’ve seen on Indeed, but nothing I truly am excited about, but I am feeling like my mental health is at an all time low from this job. I have 6-7 patients a night, we’re always short staffed, night shift is ruining my life, and my manager creates so much drama and toxicity. The only saving grace of my job is my coworkers, they’re pretty great, but not worth me staying. I recently just had 10 days off (vacation plus I called out because I was struggling with anxiety) and I was actually feeling better and like myself again after a year, and I think it’s really showed me that I need to put myself first and take the leap and quit.

I know it’s stupid to quit without another job lined up, but I can’t imagine waiting and going through a whole interview/hiring process and THEN putting in a 4 week notice, I feel like I need to just get out asap, what do you think I should do? Has anyone else been feeling like this or just quit their job? I’m currently sitting here anxious and wanting to cry because I have to go back to work tomorrow, so any advice or encouragement is appreciated lol.

update!!: I ended up contacting the per diem staff within my employer system and I just interviewed with them!! The position has way more flexibility and I am not tied down to just bedside, there’s chances for me to do out patient too!! I haven’t even officially accepted (or let my manager know lol) but I already feel like a weight has been lifted!!! There is light at the end of the tunnel y’all.
