"High-strung" describes a nervous disposition — a person who reacts quickly and intensely to stimulation, who has a low threshold for stress or anxiety. It does not mean aggressive or angry. A high-strung person may be anxious, easily startled, reactive, or tense — but these are qualities of the nervous system, not of aggression. High-strung people are often sensitive, talented, and intense rather than hostile.
"Highly-strung" and "high-strung" are variant spellings of the same compound. "High-strung" is the standard American English form; "highly-strung" is more common in British English. Both describe the same quality of nervous reactivity. The choice between them is largely regional rather than semantic.
A trick to remember it
"Strung" comes from "string" (a guitar or bow string). Picture a string pulled so tight it vibrates at the slightest touch: high-STRUNG = that's how tense that person is inside.
