Answer:

Chorus of 'Hero' by Christina Perri

Explanation:

I'm the hero of my own

No one else could understand more than myself

I can overcome anything, just be confident.

I don't need other's support as long as I'm confidently brave.

I don't need to trust someone when I know they're just lying.

(I don't know if this is enough but this is all i could think of. Hope it helps tho)
