Oooh, good question!

For me, frustration and anger are often linked, because I don't tolerate the feeling of frustration well. I like to feel in control, and frustration comes when something doesn't happen the way I want it to.

If the frustration comes with fear ("the world will explode if this isn't done the way I want"), hopelessness ("nothing ever goes right"), powerlessness ("this is defeating me; I can't do it), or grief/deprivation/loss ("I really wanted this and I can't have it"), then anger tends to flare up to hide those vulnerable feelings.

I had never thought about how frustration is linked to fear, salukigirl. That is so interesting!
