I think you have to finish what you have "started". You probably have to formally drop out of high school in some way and then decide what route you would prefer.

Personally, I would not worry about the future until I had worked through why you are not going to school now, whatever is going on now. You cannot live in the future and on what you should do in the future/future plans; you have to deal with your depression or stress or whatever is keeping you from going to school now. Otherwise, you will just keep having the same problem; whether you are taking GED classes/coaching or trying to take classes online or whatever.
