I'm starting a journal. You guys doing that?

I've said it a lot of times. Depression fucks up your memory. The last four years are a complete mess inside my head. From the middle of 2013, up until now it's almost impossible to me to say what big event came after another. I hardly remember what I was doing during the mob and I sometimes have trouble putting the last few days together (though this particular month doesn't count much...)

Today I was looking through some photos from last year and I showed a few to a friend, who also could hardly belive that it was only an year since these things happened. So I decided to start a journal. I downloaded an app on my phone to do that. I wanted to ask you guys, what are your experiences with journaling? Did it help your memory? Did it help your depression in other ways? Anything you have to say is appreciated.

P.S. I decided to use an app called "Journey", because it allows for multiple photos per entry and doesn't keep my entries on a proprietary server, but it's not entirely what I'd like to use. I'd like a little more settings to tweak and skip the auto backup. If you know some android app that allows for multiple/unlimited pictures/videos per entry and keeps my entries entirely on my phone, please tell me.
