要表达“我感到绝望”这一状态，feel 用作连系动词，后接形容词 hopeless 作表语。使用名词 hopelessness 会让 feel 变成及物动词，与本意不符，且这种说法不自然。若要用名词，可改为 I feel a sense of hopelessness，但最自然的修正是 I feel hopeless。
Not this
His hopelessness to the future is growing.
Use this
His hopelessness about the future is growing.
“对未来的绝望”中，汉语的“对”不能直译为 to；英语中 hopelessness 后接 about 表示“关于、对于”。该句想表达“对未来的无望情绪”，所以应说 about the future，而不是 to the future。
