Quotations about:
    heartache

The person who is sick in the body needs a doctor;
someone who is sick in the mind needs a friend
For a well-meaning friend knows how to treat grief.

[Τῷ μὲν τὸ σῶμα διατεθειμένῳ κακῶς
χρεία ‘στ’ ἰατροῦ, τῷ δὲ τὴν ψυχὴν φίλου·
λύπην γὰρ εὔνους οἶδε θεραπεύειν φίλος.]

Menander (c. 341 - c. 290 BC) Greek comedic dramatist
