I honestly feel like I'm in way too deep

Started a new role lately in data analytics and within 2 weeks already immersed in a 1500 line SQL query with dozens of crazy calculations transformations references tables that look almost identical with no documentation no notes nothing. It's so stressful and I already want to quit. I feel like I'm just days away from giving up and failing.



Anyone been here? How do I build my confidence?
