If you pack in your current training before at least a basic qualification then should you flounder in reaching for your goal, you will have nothing to fall back on.
I think that were I in your position then I would continue my training and once I had achieved a qualification that would gain me employment, then I would change direction.
I have seen far too many do as you seem to desire and fail, ending up with nothing. But that is only my opinion.
Best Wishes
