I don't think it is a component of BP

Hiding it - think of it more as a personal issue that will stay personal instead of thinking of it as a secret...of course key people need to know.

Not wanting to hurt people - not sure if this is combined with the first part - Did you mean to hide bipolar so not to hurt people? If you are hiding from key people - then you may want to rethink this.

I see both as fairly normal for people.
