I don't understand 歌詞

賑やかな時間に別れを告げなくちゃ
満たされ過ぎて明日が見えなくなる前に
What do I need？
I don't understand no more
We are forever young
So don't pull me under
You stay forever young
We stay forever young

悲しむ余裕などまだ無かったあの頃
立ち止まる勇気に気付かされたこの頃

Where do I go？
I don't understand no more
We are forever young
So don't pull me under
You stay forever young
We stay forever young

You don't understand no more
We are forever young
So don't pull me under
You stay forever young
We stay forever young
