They mention journaling, which is reported to be as good as anti-depressants. I was on anti-depressants for several years and they caused me to have side effects that I don't ever want to have again, so I am in the process of trying to kick them for good. Journaling has no side effects that I know of, unless it would be a tired hand or paper shortages. I personally think that the act of writing things out by hand is therapeutic, rather than typing them, but if you want to try typing them, by all means, try it. Report back here and let us know if it helps fight the darkness.
Another one that I try is a modified cold shower. I just turn the cold on at the end, rinse my hair,
which makes it shinier (bonus) and hopefully, benefit from a better mood.
I also make my bed each day, or really, my husband does it. My reading this article for the first time, coincided with our family getting a new dog who likes to chew his chewies on our bed (messy!) so when I started making the bed, it gave us the bonus of not having his chewy mess on the sheets. I do have to wash the bedspread more frequently than I used to but it's better on than the sheets. This caught on and now my husband does it every morning before work. It does make me happy to walk into the bedroom and see the bed made up and looking pretty.
This particular article has a LOT more stuff and you definitely should go read it. My favorite it is to make one audacious request per week. Hey, you never know what might happen!!!
Keep on fighting the blues! It's winnable!
