It seems for me that they both get kind of jumbled into one. When my anxiety gets bad; I get depressed, and then get really negative and then I stop feeling as anxious when I cry a lot, but then I slip into a deep depression. So I know what you mean and it's hard to tell the difference sometimes, but neither here nor there, we suffer from both of the disorders (a/p & depression), and sometimes it's hard to get through the day. I would have to say is just wake up in the morning with a smile on your face and think positive.
I try to stay positive even in the worse of times, when my anxiety/panic is at it's worst, or when I'm extremely depressed. I know it's hard, but you'll pull through.
We're all here for you. :)
BTW- I'm always worried about my mother as well, because she still smokes and I wish she would quit for her health, and sometimes I worry that she may develop Alzheimers because her mom had it and then I panic for her health and yeah... well that's A/P for ya LOL
So then I calm down, clear my mind, and just meditate. (or try to)
Sincerely,
