Should a signpost be a dilemma or is being a problem enough?

Yes.

I thought that part came after the basic PRCO stuff. I’m still stuck on making one thing lead to another without possibly bleeding into OS or RS (wanting to feel useful and to belong to a group despite raging anxiety would involve other people, so I don’t know what belongs in MC or not). It’s a holistic story form, so I don’t know if that’s part of the problem.
