Having dealt with depression in my past I know from experience that it is not something that you can just snap your fingers and get over as nice as that would be. For me depression happened at a point in my life where everything just seemed to be way beyond my control and after holding it all in for too long I just kind of went kaput and laid in bed without an apetite staring at the ceiling for a month.
After about a month of that and a break down at work I decided enough was enough and went on a low dose anti-depressant for about a year (Cipralex). The first two weeks of anti-depressants were pretty rough. My apetite didn't return right away and no magical happy fairies appeared to make it all go away. I also got jittery and yawned all the time, like all the time. But it didn't last. After about two weeks ago I calmed down to the point where I could look at food again and actually want to eat and wasn't all shaky and yawning. My attention span came back as well. I went from not being able to read two pages of a book to reading four or so 500 page books over two months (from the Wheel of Time series if you're curious), you literally could not tear me away from a book, just like my bibliophile self was used to before everything went all crazy pants in my brain.
In my opinion anti-depressants are a way to get out of the place where you don't want to get out of bed. They aren't the full solution, not by a long shot but they got me out of my bed and wanting to do the things I loved, like reading.
You also need to be ready to want to help yourself. If you don't want to help yourself chances are you won't get better and you won't be happy. If you want to get better, you have to want to get better.
