Starbuckone, apologies not meant any criticism, i know they can come on any time, i did try and get help, but at that time, it was put down as teen problems, no one really knew what it was then, much more info now, but anyone who says pull yourself together needs a swift kick up the backside.
Often triggered by a traumatic event, though you won't necessaily attribute it to that, and can take long time to work out, what works best, but doctor is definitely the place to start. Its banded around so much, but unless its happened to you, you would not know how bad it can be.
