Accepting a management position likely won't make the feelings you have disappear. You may not even like the day-to-day job of managing more than being a engineer, and there will still be people younger than you are higher than you on the totem pole. There is always a bigger fish. Solve the "no motivation for the interview process" problem, and you may find that a change in scenery can fix the rest of the problems you are experiencing.
