Sounds like something I also remember feeling like. And, when it comes to themes like these, I think there just aren't any clever life hacks to it. And it might be that every person needs to find their own answers which happen to work in their personal situation. In my own long slow process it has often felt like this:

Looking over a valley I saw a hill on the other side and knew that I wanted to get there. So I started trekking through the valley, but once I get there a thick mist arose, and I couldn't see a thing. For most of the time it felt like pointless struggling with no gains. And there was no way to know if I'm walking in circles or actually going somewhere. But also since just sitting on one spot didn't feel like a real solution, the only thing to do was to keep orienteering based on the memory of that clear view over the valley. And eventually it started to feel like the mist getting less dense, it becoming easier to travel. I realized in the mist I had lost directions and didn't get to the hill I tried to head towards, but ended up in another place which is not bad - and this place is not a final destination, but a beginning of yet another chapter in the adventure.

Hmm, this metaphor fails in some essential sense, as I also feel that in some way the "moment of despair" is actually essential and necessary stage in the process of getting rid of the old and transitioning into something new - in between there is bound to be the unpleasant stage of "not-really-being-anywhere-anything", and the painful thing is that this stage can last for long, and there is no way to fast-forward through it.

This is how I feel about it. Hehe, I maybe could try to write something more elaborate some other day.

But, to end this comment a little detail; When I was thinking of different ways to fund Ancient Savo development, I recognized that mood that feels like paranormal superstition saying that "if you do it big and officially apply for funding from any source, that is magically going to attract problems, yes maybe giving you the money but at the same time bringing unforeseen big problems ruining the entire project." And instead of battling that emotion I decided to allow it to be. And so far it has been okay; no major funding, but no major catastrophes, and the project growing steadily towards an official release.
