So I'm running into some tense issues with first person.
How do I differentiate between what the character is seeing/experiencing and what they're thinking?:
The room was dark. I couldn't see a thing.
How the fuck am I going to get out of here?
Without any kind of indication, it seems far too easy to get confused by what the character's thinking and what they're noticing.
I'm not a fan of using special markets (i.e. [thoughts]), or italics. The latter kills italics as a point of emphasis and the former feels clunky to read. I think the solution is stylistic? But I'm not sure.
