Feeling stuck at 30

Hi All, I’m 30, single, and working a 9–9 WFH corporate job. The workload is always heavy, and Manager keep pushing more work, leaving me drained. I feel broken inside—no colleagues to interact with, no social circle, weekends wasted scrolling. Out of stress and anxiety, I’ve started smoking more frequently just to cope. I don’t have a professional degree, so switching jobs feels risky as most companies prefer degree holders. I feel lonely, confused, and scared about my future. Has anyone else gone through this stage? How did you rebuild your career, health, and life?”
