I don't remember having panic attacks that early, but I do remember feeling "sad" that early. I NEVER felt "happy" as a child. In fact, I didn't know what happy felt like until I FINALLY got on an antidepressant that WORKED and that was just 20 years ago - when I was in my 40's. That's pitiful.
I came from a VERY dysfunctional family - and all 4 of us kids are depressed. So it's no wonder there was no happiness in that family. Hugs, Lee
