How much of your unhappiness is your job, or more so a function of having a continually growing list of responsibilities that can become to feel suffocating (e.g., marriage, kids, managing people at work, etc).
Because it can be a taboo subject, I’ve seen people misattribute their unhappiness to a single thing when it’s really a culmination of many things … and their isn’t a way to “fix” the unhappiness (you can’t “un-have” a kid)
