How to say "unbearable" in Japanese

  expression, i-adjectiveFor a feeling or sensation so strong you can hardly endure it — pain, longing, or delight; the emphasis is on being overwhelmed, and it is often used of things you love or crave.
  このにおいはたまらなく嫌いやだ。↗

  This smell disgusts me.
• やりきれないCommon
  i-adjectiveFor situations rather than sensations: something — a task, a hardship, an unfair state of affairs — that is too much to cope with and feels impossible to see through; the nuance is frustration and weariness.
• かなわないCommon

  私は退屈たいくつでかなわない。↗

  The boredom is unbearable.
