Quitting from not a happy place but?


I have the following situation, as put in a model:

C: For 6 years I have been working pretty intensely for a company, with very long hours and recently a streak of days where I finish at 3am every day. It’s not a thought – it’s a fact. I also have a wife who does not earn much and two kids under 5. I am the only breadwinner. But I cannot do it anymore, I want to quit.
T: I cannot do it anymore. I don’t know what I want.
F: Disorientation
A: Buffering
R: It’s more and more intense and nothing changes (?)

It seems like a vicious circle that I don’t have the energy and focus to break. Help!
