As my advice is not always the best, I'm in the same boat as you. But what sort of helps me is that I think what is the worst possible thing that could happen when I start this job. The worst thing is that I could get fired on the first day. If that happens then I look for another. What if I have a panic attack while their training me? Then I will make sure I take a 1/2 xanax or ativan b/4 I start the job. See where I'm going with this. Try and think about what could happen and try and find the best solution before you go to sleep tonight and maybe it will calm you down a bit. I know it's not the best advice but it's just one of those things that works for me. Good Luck

Hey gingersna...
Talk to your doctor, or see if there's something she can do during these high stress times. Don't get yourself all worked up when people tell you that you'll be fine, or its ok. The truth is that no one knows your every thought...and they're just trying to offer you comfort the best way they know how. They mean no harm, they may not know how to help you. But listen, talk to your doctor, and don't drink caffeine during your first week of work. I wish you much luck...maybe you can do some exercise in the morning to get some of those antsy feelings out.
Good luck!

I think hopeless is right, my councillor has taught me to turn around my thoughts like this, its called turning Activating event
Negative Thought
Into A Realistic Thought.
It takes practice.
maybe you could spend some time writting your 1/3 thoughts down in order to learn how to think realistically.
Do You take meds for anxiety?
If not you might want to talk to a doctor and councillor.
Im in the same boat as you, i have a written and proceedure exam to take shortly, ive been making myself sick with so much anxiety so ive decided thats it, im just going to take exam soon as possible and pretend the evalulators are not there or i dont care they are watching me or there a person just like me, if i fail i can go back and retake and ill know what to expect.
Good Luck!!
