[masaegu]

Not that I possess a non-Japanese-speaking mind, I could kind of understand that both 預かる and 助かる woud be difficult to put to use for the learner.

This is why I hesitated for a minute to give you the translations. If you translate, the two will only be harder to grasp than ever with regards to the subject and object of the sentences in which they appear, especially with 助かる.
