Can someone tell me what this spanish song is about?

Question

Hundida yo estaba, ahogada en soledad

Mi corazón lloraba de un vacío total

Todo lo intenté

por donde quiera te busqué

Eras tú mi necesidad

Triste y desolada ya no pude soportar

Más desesperada era imposible de estar

Todo lo intenté por donde quiera te busqué

Eras tú mi necesidad

Alcé mi rostro y...

Coro

Llegaste tú y todo cambio

Llegaste tú, la esperanza triunfó

Llegaste tú, volví a nacer

Por tanto tiempo quise

encontrar la solución

a ese gran vacío que llevaba en mi interior

Todo lo intenté por donde quiera te busqué

Eras tú mi necesidad

Alce mi rostro y...

Coro

Llegaste tú y todo cambio

Llegaste tú, la esperanza triunfó

Llegaste tú, volví a nacer

My heart cried from a total emptiness

I tried everything, I looked for you everywhere

You are what I need.

Sad and desolate, I couldn't stand it any longer

It was impossible to be any more desperate

I tried everything, I looked for you everywhere

You are what I need.

I raised my head and...

Chorus

You came along and everything changed

You came along, hope triumphed

You came along, I was born again.

For so long I wanted to find the solution

to that great emptiness I carried inside

I tried everything, I looked for you everywhere

You are what I need

I raised my head and...

(repeat chorus)
