I read somewhere that common advice tells you that to access those inner character feelings, you should pretend to have coffee with your character (to get to know them), but that really, you don’t want to ask yourself what your character would say to you (the author), you want to ask yourself what the character would say to themselves.
Annnd you also want to ask yourself what your character is FEELING while you’re asking her those icky questions. And what she might answer to obfuscate. Play the outer spoken with the inner dialogue.
External dialogue: Oh, no, I’m fine. Really.
Internal: WAHHHHHHHHHH! SOB!
