What does it mean by "came away" in this context? Below is an excerpt from the book, After You. The protagonist lost her loved one a while back (since he, Bill, killed himself) and she's now at a grief counseling session. 'You feel guilty about Bill's death because you feel you could have stopped him?' I pulled at a thread. **When it came away in my hand it seemed to loosen something in my brain**. 'Also that I'm living a life that is so much less than the one I promised him I'd live. And guilt over the fact that he basically paid for my flat when my sister will probably never be able to afford one of her own. And guilt that I don't even really like living in it, because it doesn't feel like mine, and it feels wrong to make it nice because all I associate with is the fact that Bill is dead and somehow I benefited from that.' I don' understand the part marked in stars, especially the meaning of "came away in my hand" and also what "it" exactly refers to in "when *it* came away in my hand...". Thanks in advance.
