The chill in my bones

When everyone agrees that Bucky Barnes in better off in cryostasis until they figure out how to fix the programming in his head, Natasha underestimates just how deep the programming in hers goes and when she watches him walk into the cryotube to surrender to something he thinks is for the best, a memory that she's long since tried to avoid thinking about breaks her mind apart and causes damage that she'd never thought was possible... And the price may be more than anyone could've ever guessed.With Natasha no longer in control of her mind, the Black Widow may very well destroy the life she's fought so hard to create for herself away from that dangerous past of hers but even she's known all these years you can't run from your past forever...From the prompt: It's easier than you think to lose everything you love.
