Tell them you need to fly on a plane and you have major anxiety. They will prescribe you something, but a DR is never going to give you very many of these pills unless your diagnosed with some major panic disorder.
I went to my regular DR 4 months ago and was prescribed 15 .5 mg of Ativan.
To be honest, they just make you tired. It's a lot easier to just get rid of your panic attacks on your own by saying positive things like:
"I'm not going to die, I'm just anxious."
"My left side of my body is numb, I'm just really anxious. I've got to take deep breaths"
Deep breathing is the best to calm me down.
When you get stressed out something else you can do is slowly relax your muscles. If you're standing up, just relax your shoulders and arms and take a deep breath. You'll eventually do this every time you're stressed out.
The reason your DR prescribed you the SSRI's are simply because they do help with anxiety. It's not just depression. I know for a fact that when you're on anti-depressants things are a bit easier to handle. Not because they change who you are, but because they get rid of some of the physical symptoms you might be having.
Maybe you should try a different class of anti-depressant. Don't go straight into ativan because you're Dr won't give you very many anyways.
