Out of a good sleep

I can't understand why I wake up in the middle of the night (last night at around 1 a.m.) to find that I'm in a cold sweat and feeling like life is crashing in on me.  Yes, I am being downsized out of my job, but I have six months pay w/ benefits as a severance.  I'll find a job.  But waking up with this sense of panic and my stomach in a knot, then not being able to fall back to sleep certainly doesn't allow me to be at my best.

I'm taking 40mg of Celexa a day and using .25mg of Xanax as needed, plus starting to see a LCSW who uses cognitive-behavioral therapy.

I'm now stressing about having to live with this fear and panic for the rest of my life.  I guess I need words of encouragement that there is an end to this fear and that finally I'll be able to have some peace.

Thanks for reading.
