German tends to have a word for everything because of their proclivity for mashing words together. In fact, it's a fun game taught to kindergarten students. So, if it doesn't exist, don't be afraid to make it up!
For example: das Meerschweinschen (guinea pig)
The stems are das Meer (sea) and das Schweinchen (little pig). Not of the ocean and not a pig, but still a guinea pig.
I'm sure you can guess that "das Bananenbrot" is banana bread. Ignore that there is a random n in there, language is a tricky beast.
Also, angst (a German word) made its way into English without much trouble. So, making a word might be your best bet.
Maybe you'd want to go with something like Exaltierheitangst?
Exalltierheit is excitement and angst is angst, but, together, the average English reader would comprehend something like Exalting and High Angst.
They're both feminine nouns so there's no worry about endings and what not, and it doesn't feel like there should be any additional vowels tossed in (that's kind of touch and go depending on your fluency level.)
Don't be afraid for it to look weird either. As long as you couch it in a paragraph, people will be able to readily understand the meaning.
For example, Schneeeule looks really weird but if I talk about the white plumage of the Schneeeule (snowy owl) and its nocturnal habits then it's not a problem. Schnee (snow) and Eule (owl).
