Fibromyalgia and depression go hand in hand. Together they go. You barely see one without the other when you are suffering from fibromyaglia. But you can over come this. It isn't easy and takes a lot of work, but it can be done. If the depression gets too bad, come on over to the depression forum. There are a lot of understanding members there who can offer you some support.
I hope that you feel better soon. Like I say, pop into the depression forum and get to know everybody.
Take life one day at a time. Try not to dwell on the past, or worry about the future. You will find out with fibro that is about all that any of us can do anyway.
