Space_Helen's journey

I'm feeling desperate to leave my current job at a large organization where I've been working for about 4 months. I took this customer service role after my last contract ended to avoid a gap in my CV, but I've realized that this position is not a good fit for me. The work environment is disheartening, especially with a colleague who bullies others and the management's lack of action on workplace issues. I dread going to work every day, and the rude customers only add to my stress. My mental health is suffering, and I'm not sleeping well. Although my manager is pleased with my performance, I don't feel the same way about the organization. I'm actively applying for new jobs, and I'm considering giving my notice, which is only a week. Living with my parents gives me some financial flexibility, but I'm torn about whether leaving is the right decision. I would appreciate any impartial advice on what to do next.
