Replying to your first edit. Trust me I don't care. I'm relatively sure I'm not going to apply to YC so I can tell here. I know what it feels like. The hyperbole and half post resonated with me. Things are happening, I know they are happening, but I don't know that these are symptoms for something. If you've been through depression, I think you know what I'm talking about. You can just see, nothing matters. Why am I getting up? Why am I poking a fork on a grape and eating it? I'm washing a plate... what's going on. The water is running from the tap and hitting the sink and making a sound. What's the point of that? What's life anyway? Just a bunch of random chemical reactions. Basically I'm ending up think (paraphrased) "What the fuck is actually going on in this world?"
I didn't know that was called depression until I read that post...
Note that there is an important part of the definition being left out: "... significant impairment in social, work, or other important areas of functioning".
