Quiting my job..

Hey guys,

I work as mechanical engineer at an office. We do MEP designs. I'm at this position 1 year and 2 months now. My passion is data analysis and in general this sector. I'm thinking to quit but the backup plan I have is to work as driver in a rental car office for some months till I get my certifications and better knowledge on SQL, power bi etc. My bachelor is production and management engineering and my master is MBA.

But the thing is that my mental health is a mess at the work I am now, I don't do things right because I'm not interested at this position and it gets worse every day..

If you have any recommendations I would appreciate it.
