I'm not really good with words but I've been watching your progress on AS for a while now and let me just say that I really admire how you've been improving the game constantly. You're a real Ren'Py wizard in my eyes, be it mechanics or UI design.
Praise aside, working on a long-term project is quite grueling, especially with ambitions like yours. And I can totally understand that you feel this way.
So I wish from the bottom of my heart that you will get a good, restful break and eventually find that spark again.
