When I lost/gave up my job and left the office environment a couple years ago, life became less ordered and much less safe and my anxiety levels shot through the roof. But my ability to be creative grew and like you I had various outlets, none of which I could focus on - writing, felting, new crafts I kept discovering and trying out, gardening, expanding the livestock to care for, rediscovering various forms of music and dance, spiritual work of all kinds of depth, challenging myself to tackle things I was always convinced I couldn't do, like art.. and every job I applied for I got to interview stage and came second because "the other person just seemed to want it more" - which I discovered was true. At some level I needed to be out of the system for my health and growth and that is what manifested in my life.
It settled a little but not much, I just got used to what I called "riding the wave of chaos" and letting the various forms of expression channel the mass of processing I was going through internally, wave upon wave of it. I think for me it was about giving up that expectation of control and order and surrendering to the flow and the many ways creativity can be expressed. Life intervenes all the time and planning even a day ahead is rarely successful. I now doubt my ability to return to a "workplace" more than part time, maybe not even that, I seem to avoid finding out
but I've never had more sense of who I am or what is important to me and been able to flit between ways of being that person. And I am doing the one thing I wanted to do which I'd never have done until those distractions of "normal life" were removed, piece by piece. And the distractions of "other forms of creativity" allowed me to work through the things I needed to before that one thing became not only possible but real to me.
From what you've been saying, this project is important to you and will be completed, by a direct or indirect route. Maybe it is the focus that you will need to cope with the lack of work, or maybe the lack of work is what will give you the freedom and time to get it done. The chaos of the transition is energy to feed your intention, the other creative activities are just a means to the end you have set, ways to tackle barriers and obstacles within you so that you can succeed. Well that's my belief anyway
