your mood is always oscillating between

[GoodTaste]

I made the following (two sentences). I wonder whether it sounds natural in native English speakers' ears. Your comment and editing will be appreciated.

There is an emotional spectrum for every one. At one end is happiness, the other is suffering, and your mood is always oscillating between.

There is an emotional spectrum for every one. At one end is happiness, the other is suffering, and your mood is always oscillating between.

Here is a possible rewrite.

There is an emotional spectrum for everyone. At one end is happiness, at the other is suffering, and your mood is always fluctuating/swinging between the two.

"everyone" is a single word.
In my opinion you need to repeat the preposition "at".
I feel that both "fluctuating" and "swinging" are more natural than "oscillating".
You could finish with "… between them", but I feel that "… between the two" is better.
