become a bit of a basket case due to fear or anxiety
Calling someone a 'basket case' is an insult and implies that the person you are talking about is crazy. Be careful using this expression in public. It's generally an insult about someone's mental or emotional stability, although a lot of English speakers might use it jokingly. A 'basket case' can be someone who is considered to act a bit crazy or have trouble dealing with other people in a personal or professional capacity but it can also be a situation or an organisation which is considered to be unstable or to be a risky investment. You can use this in either social or professional situations, but if you're describing someone when using it, be careful who hears you say it!
