ELI5: How does the emotion of fear lead to the emotion of anger?
gpt
Emotions are like shortcuts to certain behaviors that are meant to help you deal with the situations that trigger them. 

Fear helps keep you safe in potentially dangerous situations by encouraging behaviors meant to extract you from those situations.

Anger is a response to unresolvable problems that can help you break through whatever barriers are in the way preventing you from figuring out a solution to the problem, which is why people are often more motivated to act in general and more likely to resort to reckless or violent behaviors when angry.

If you are unable to resolve the situation that is making you afraid, this can result in an anger response.
