This is a terrible position that you`ve put yourself in.but that one has taken quite the dump in its ability to provide the basic needs it was supposed to serve. But it still steals away the time, energy and focus.
I think you should get rid of this particular day job, its killing you.
Have you lost your drive for follow through?
Absolutely not.
Its not something you can lose.
BUT it can be drained out of you each day by a dead end job, thats for sure.
I wouldn say that you`ve hit a "wall", but you`ve tumbled onto a "drain".
My advice is identify what steals your time and energy the most and get rid of it.
