I was wondering about this years ago too. And I found too many answers to this question and how important that is.
Where to start...
Nothing is not exactly nothing. The energies just become "more subtle". The problem with the subtle energies that you need an extremely quiet and still mind to "notice it". And the worst part with these energies that they were "always around you". This is why you are so used to it you never "noticed it". God is everywhere. And the light of God is invisible. The Dao is also invisible and you are unable to feel it.
This is only true to a point. Because when you realize how to "see it" it becomes "visible". It's just you cannot look at it the same way as you currently look at things IRL.
Emptiness is not actually empty. When you reach a point where you think "nothing is there" you can slowly and extremely cautiously take a "step" into the "stream" and see all the things that are "there". Now here comes the dangerous part. The "stream" is quite "still" at the "shores". But as you walk "into it" it gets wilder. And you will need an extremely calm and still mind for that to not get "washed away".
Your life will get extremely interesting when you will be able to "enter the stream" because that way you can communicate with all aspects of reality. But there will be a time when you cannot stand the "noise"/waves further. And you need to go to a "quiet place" to "rest".
Your frustration is normal on the path. Everyone under a proper master usually asks at 1 point on the path "what is the point of this". Because it is an extremely grindy and boring repeating exercise that they need to do to reach the "Next stage". It is needed to be "Boring and repetitive" because it trains a "muscle memory". That way it is "safer". There is that "teaching method" where they throw you into the water and as you try to "survive" you instantly figure out "How to swim" and the other when you have to practice the movements for weeks before you can get out of the "kiddie pool". The problem with the "getting thrown into the deep end" is that you might drown or it will be so traumatizing you will never want to go into water again.
