In short
If you hate your job, first pin down whether the problem is the boss, the schedule, the pay or the work itself, because each has a different fix. Change what you can now, like shifts or teams. If it is the work, pick a target career, find training you can do around your current job, and set a date to leave.
Name the problem
The boss or coworkers
A transfer, a new location or the same job at another company may fix it.
The schedule
Ask about shifts, or look for the same skills in a job with set hours.
The pay
Check what the job pays elsewhere; a new credential may be the lever.
The work itself
This is the one that needs a career change.
If it is the work
Take the what career is right for me quiz to find paths that fit your life now. Then give yourself a timeline: three months to choose and enroll, then the length of training.
Protecting yourself meanwhile
Keep doing solid work so you leave with a good reference. Save a little each month toward training costs. If you are struggling with your mental health, talk to a doctor or counselor; that matters more than any career plan.
Questions people ask
Should I quit my job without another one lined up?
It is risky unless you have savings. Most people do better training while still employed.
Is it normal to hate your job?
Very common. It is a signal to change something, not a personal failure.
How do I figure out what I want to do?
Start with what you do not want, then test options with a quiz and conversations with people in the field.
