For SFU, it's "Breathe Me" by Sia. From the SFU forum:
Help, I have done it again
I have been here many times before
Hurt myself again today
And, the worst part is there's no-one else to blame
Be my friend
Hold me, wrap me up
Unfold me
I am small
I'm needy
Warm me up
And breathe me
Ouch I have lost myself again
Lost myself and I am nowhere to be found,
Yeah I think that I might break
I've lost myself again and I feel unsafe
Be my friend
Hold me, wrap me up
Unfold me
I am small
I'm needy
Warm me up
And breathe me
Be my friend
Hold me, wrap me up
Unfold me
I am small
I'm needy
Warm me up
And breathe me
Edit: think I just answered it for the wrong episode 😱
