Analysis of Howls moving castle

A Heart's A Heavy Burden
I feel terrible, like there’s a weight on my chest
Im singing lulabys like theres nothing in my life
I feel like I’m getting old everyday
then someone made me a old women
and I’m going to die sooner.

Why everyone is talking me like I’m just a ghost
wait maybe I’m a ghost
but Howls is here for me to stay
is kalcifer howls heart?
are we just people on the galaxy?
there are  wars and fights in our life.

What is going on?
people are worrying cause they
think they are going to die in wars
if we save them will they change
their mind?
