Psalms 55:17 Evening, and morning, and noon, I meditate, and make a noise, and He heareth my voice,
The verse centers on "desolations", "upon", "down", "sheol--alive", "wickedness", "dwelling", and "midst". It is saying that the verse draws attention to "desolations" and "upon", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "When together we sweeten counsel Into the..." into verse 16's "I--to God I call and Jehovah saveth...", so "desolations" and "upon" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "desolations" and "upon" with trust shaped by these words, not by a vague optimism outside the passage.
