Word to describe the fear of unknown future

Is there any word to describe the fear of unknown future? Like when you cannot anticipate your future, you don't know what will happen or what can happen, not near or immediate future, but some future far away.

Like what will happen five years from now? You can't control it so you're fearful.

You may consider using apprehension.

In a given situation, angst or dread may also apply. Angst is usually more diffuse, and not necessarily about the future. Dread is more focused, often on an anticipated event.

At lower levels this fear is referred to as ordinary “worry;” at higher levels it may become so intense that it can be called “anticipatory panic.”
