How to say "heartfelt" in Japanese

• 痛切つうせつJLPT N1approx.Common
  na-adjective, nounCovers heartfelt in the sense of an emotion felt keenly and deeply, often with a painful edge; typical of feelings such as regret, sorrow, or gratitude that pierce the speaker.
  彼女かのじょは悲かなしさがあまりにも痛切つうせつで涙なみだも出でなかった。↗

  Her grief was too acute for tears.
• 満腹まんぷくCommon
  no-adjectiveNot a word for heartfelt emotion: it means full, having eaten one's fill, as after a big meal. Its 'heartfelt' gloss is marginal, and reaching for it to describe feelings would be a mistake.

Choose 痛切 for heartfelt emotion felt keenly and deeply; 満腹, though it carries a 'heartfelt' gloss, actually means full from eating and is not a word for feelings.
