Good Morning Tiamarie,
I am sorry you have received the news that your daughter will be going overseas for 4 year. Now let's get you on a plane and over to visit when your ready. You cannot drive, sweetie...........hugs.
When it comes to panic attacks remember this, just because you have these sensations doesn't mean you are crazy. These feelings are just unpleasant and frightening, not dangerous. Nothing worse will happen to you. Don't indulge in stinkin thinking, "Why can't I be normal ? Why does this have to happen to me?" Just accept what is happening to you. If you do this, what you fear most will not happen.
You are in control of the situation. Keep posting here and let us help you. We care about you and take a look at the online CBT if it appeals to you. It is free.
