Word to describe being apprehensive about the possibility of something you’re excited about NOT happening?

Is there a word to describe the emotional state of being simultaneously excited about the prospect of something and dreading the prospect of it not happening? The closest thing I can think of is "disappointment" but I don't think that covers a future tense hypothetical.

The use of the word would be something like:

"I am excited because I think they're going to offer me the job but I'm worried that they won't."

Would transform to:

I am (word or phrase) about the job offer.

You are on tenterhooks about the job offer.

OED

to be on (the) tenterhooks: i.e. in a state of painful suspense or impatience:

Worldwidewords.org explains further

It comes from one of the processes of making woollen cloth. After it had been woven, the cloth still contained oil from the fleece, mixed with dirt. It was cleaned in a fulling mill, but then it had to be dried carefully or it would shrink and crease. So the lengths of wet cloth were stretched on wooden frames, and left out in the open for some time. This allowed them to dry and straightened their weave. These frames were the tenters, and the tenter hooks were the metal hooks used to fix the cloth to the frame. At one time, it would have been common in manufacturing areas to see fields full of these frames (older English maps sometimes marked an area as a tenter-field). So it was not a huge leap of the imagination to think of somebody on tenterhooks as being in an state of anxious suspense, stretched like the cloth on the tenter.

You are anxious about the job offer.

Anxious:

wanting something very much, typically with a feeling of unease.
