For me, the song that describes bipolar from my perspective is 'Nothing More' by Crowbar. They are a sludge metal band from New Orleans. The lyrics from this particular song are the following. It also describes the abandonment I experienced with my dad.

Eating away at my body and soul
so tired of all that you've taken
i've always known that i'd be on my own
not knowing how hard i've fallen...
... in your arms

now it's gone

been so long

its all gone

believe in all i've ever known
left me to die here on my own
you took it all and left me
you took it all and left me

if i survive long enough to come back
won't you forgive me for falling...
... in your arms?

now it's gone

been so long

its all gone

believe in all i've ever known
left me to die here on my own
you took it all and left me
you took it all and left me

This disease has taken so much from me and this song describes it perfectly for me, tbh.
