When troubles catches up with you, a child's shirt fits you.
When you are caught up in a really difficult situation, you find yourself doing desperate things you never expected.
A simple and straightforward proverb, the equivalent saying in English is "Desperate situations call for desperate measures".
Patois: Yuh cyaan duh noh'n bout it fi now, suh yuh jus haffi run wid wah im did tel yuh. Memba seh wen chubble kech yuh, pikni shut fit yuh.
English: You cannot do anything about it now, you just have to accept what he told you. Remember that desperate situations call for desperate measures.
