wil shipley writes about his depression :

I’m always fighting depression. It’s there, waiting for me. Some months I’m great and I function like a normal person, and I think, “Yay, I’m done! Thank goodness that’s over!” Then I’ll have a week so dark that simply taking mail out of the mailbox seems like an epic struggle. And I remember, oh yes, right, you aren’t going away. Because you’re my brain. You’re my chemistry. You’re me.

i don’t like his software (gasp!) but i like his writing. here he writes about love, amongst other things.
