in a stew
Agitated, alarmed, or anxious. For example, Mary was in a stew about how her cake was going to turn out. It is also put as get in or into a stew, as in Every Saturday the minister got in a stew about Sunday's sermon. This expression transfers the mixture of meat and vegetables constituting a stew to overheated mixed emotions. [c. 1800]
