'When absent from my soul's delight' was very apt with all that about;

'terrors fill my troubled breast'.

So very descriptive of Faulkland's state. ;-)

Even the lines;
Once more return'd to thy love's Sight,
Hope too returns, my Fears have rest,

Thanks Julie.
Reading the songs in the context of the play and Faulkland make them quite amusing, though that was definitely not the writer's intent, who really looks melancholic in the picture.
