First... you know we're here for you. To hear you and be your shoulder. Truth be told, you are a strong, strong man for sticking it out for six years.
Maybe it's time to take stock of who you are, what you have, and what you want. Take your W and your M out of the equation. At least for right now.
Consider... you've spent six years on this... in hindsight, taking a month off and really becoming you... JUST you... could be well worth the emotional vacation you really need at this time...
