I suffer with depression too, it runs in my family. I got to the point where I absolutely couldn't function. I would literally lay in bed all day and just cry, and this was before RAH even entered the picture. At that time I went to see a therapist and she suggested anti-depressants. I struggled a LOT with the thought of taking them, didn't want to have to take a pill just to feel "normal". I did end up taking them and they helped a great deal. At the same time I was taking them I took a good look at everything in my life to see what helped to trigger the depression; i hated my job, I never went out and had fun...etc. I started making some changes and my depression subsided. I've since stopped with the anti-depressants, and my depression is still under control.
If you think that the medication would help I would definately give it a try.
