It seems like you just want to argue. You seem frustrated and deeply unhappy with your current job. I was that way, for times, too, so I get it.

You need to focus on what makes you happy. I don't want to dissuade you. But think long and hard about the change. Grass isn't always greener. But it can be. It may work out, it may not. The point is, it isn't a slam dunk.

Best of luck!
