Our reading
An editorial interpretation.
The speaker fears that trouble once regarded as temporary could shape an entire life. A bad summer had a reassuring limit; a bad life does not. The contrast expresses anxiety about a difficult period becoming a lasting condition, while “potentially” leaves that outcome uncertain.
