I thought that it is an interesting blog and I enjoyed reading it. I must say - I got a bit of a shock when I read the depression post though because it was such a sudden contrast to the other stuff, but that's the point really isn't it?
What I would suggest is that if you want to be honest and put those kind of posts in your blog, maybe it would be an idea to mention your depression on the About me and this page entry. I read that first, and it left me unprepared for what was on the other page.
I'm going to be starting a similar site soon, dealing with my cycling adventures in Yorkshire and Lancashire, but I'm not sure that I'll be that open and honest about my bad days (I do have them).
Keep it up!
