Hi Jana!
I find myself wanting to congratulate you for seeing your depression for what it is, but congratulating someone for being depressed sounds horrible, so... I can't quite figure how to say it, but I'm glad you've made this big step in working with your depression.
Somehow in our society there is such a stigma about depression that gets in the way of people who need help getting it. I know it did that to me for years. The truth is, almost all of us will confront depression at some time in our life, either in ourselves, or someone close to us.
Where you go from here is the big question, no? I can't tell you the road to take, but maybe I can point out some of the various roads you can choose from? (OK, I'll stop with the metaphors!) One option you have is medication - which means working with a doctor you can trust, and if you don't have one now, finding one. In the interest of disclosure - this was my first step.
Another option you have is talk therapy. Finding a counselor you really like can take a couple tries, but the work can be remarkably helpful for a lot of people. I used to poo-poo therapy, mostly because the time I'd done it before had not been my choice (teenage years, well-intentioned partents), so I never got anything out of it. In my opinion, you have to initiate and really "buy into" the process for it to be really helpful to you.
You can also try other, more alternative methods - like herbal supplements, etc. I know several people who use accupuncture instead of medication to manage depression - it supposedly activates the same brain chemicals, and essentially "resets" your nervous system. Again, this is something that I suspect will only work well if you believe in it.
Exercise can also be a good way to try to balance brain chemicals. My problem was that the depression made my energy so low, and my motivation non-existent.
Whatever you decide to do, we are here for you! I hope things turn up for you soon.
