Note: Often followed by で or a clause expressing difficulty/confusion.
The structure やら~やら is used to list two or more items as non-exhaustive examples from a larger set, often conveying a sense of being overwhelmed, troubled, or uncertain. It implies "things like A and B (among others)" and typically carries a negative or burdensome nuance, suggesting the speaker finds the situation chaotic, complicated, or emotionally taxing.
When used with nouns or verbs, やら~やら presents multiple items or actions as representative examples, implying there are even more beyond what is mentioned.
Notice how the speaker is expressing that the situation was overwhelming – not just a neutral list.
やら~やら can also be used with adjectives to describe mixed or conflicting feelings/states.
This usage is especially common when describing contradictory emotions experienced simultaneously.
While とかから~とか also lists non-exhaustive examples, it is neutral in tone and used in casual conversation. やら~やら, by contrast, tends to carry a negative, chaotic, or emotionally charged nuance. Similarly, し〜~し lists reasons or attributes but does not inherently convey the same sense of being overwhelmed.
