candid.
/ˈkændɪd/ adjective
Saying what you really think, plainly, even when it would be easier not to.
It’s all in the nuance.
Honest means you don't lie; candid means you don't hide — you volunteer the uncomfortable part.

Hear it in context.

Take it into your day.
Say 'I'll be candid' once today, then say the thing you have been softening.
