I experienced a lot of what you have written. And probably most people do. The key element to managing all of this is being content.
Now the next question is with what?
Professional life - be content with quality, hours and fair compensation. You can forego compensation for a great opportunity byt correction has to happen, its a temp situation. So think about comp carefully and balance it with the other two.
Personal life - Spend on yourself, your loved ones, on a cause. Time and money. Whatever brings you happiness. In this rat race of professional lives, we often forget to live for ourselves. Need this for family, that for partner, this other thing to signal society. Nope, you only need what makes you truly happy and it can be completely different from the next person and that is absolutely FINE (imagine someone yelling a loud, resounding fine in a positive tone, you will feel better).
I am not trying to diminish what you are experiencing but simply drawing your attention to things that could mitigate this feeling. Which I have been through enough and now become somewhat immune to, it takes time, patience and concerted effort but it can be resolved.
Feel free to ask more questions here or in DM. Happy to help!
