Yikes, that last one is really dark.
I think what I like the most about it is that you seem to be very sure of yourself and your writing. You're not holding any punches with this story, and I love to see that. I wish it had a little more of the metaphorical ideas behind it, if there are some, because I don't really see why the person is behind bars, but you could introduce that in a title with something long winded like "My Year Behind Bars of Depression" or something like that to introduce the character's metaphorical situation before presenting a very real example of "behind bars" for the reader.
