Can you do a quick outline of what's in your mind right now? I often do that with scenes that feel really vivid to me but that it's not time to write yet (b/c I write from start to finish). Like, if I know two characters are going to have a fight, I'll write something like: When M and F meet up after whatever splits them up, they're mad and M throws something about F's history at her, and she says, "Of course. I forgot who I was dealing with. You never make a mistake, do you?" beat of some sort "But maybe that's because you never do anything. You just sit there being perfect, and passive, and you're scared to actually try anything in case it doesn't work out." He comes back with something defensive, she references his sister, they leave still angry. I can't do it for every scene because I have no idea what all the scenes are, but when something's really vivid in my mind, I type it up and use it (or not) when I get to it. Could you do the same for some of the things you're worried about losing, and then have them there to use (or not) when you come back to it?
