True-Ad-9540's journey

I've been working at my current company for 3 years, and I recently transitioned to a new department after my previous role became incredibly toxic, affecting my mental health to the point where Occupational Health recommended I take 3 weeks off. I thought a change would help, but unfortunately, the new department has proven to be just as bad, if not worse. The management is unprofessional, spending their time gossiping about staff and making derogatory comments. I've witnessed them calling colleagues 'weak' and sharing personal information that should remain confidential. Since I started about 4 months ago, 5 people have already left the team, which is alarming. Additionally, one colleague speaks to me in a disrespectful manner, and others have noticed it too. The overall atmosphere is draining, and I've been applying for new jobs, but it's exhausting and time-consuming. I'm struggling with sleep, my appetite is gone, and I feel anxious all the time. I'm at a crossroads—should I take time off to protect my mental health, or will that just complicate things further? I would really appreciate any advice from those who have been in similar situations.
