I am sure Anthony is right.
But for me there were/are things that can make a short term difference for some. For me, the key to not curling in to a fetal position right away was DRUGS. WEEEEEE.

No not that kind of drugs. Medication for my condition. Two medications helped me.
The first was/is Klonopin (generic - clonazepam). This stuff is key to really helping me with my chronic, tital wave size, anxiety. It is also inexpensive as it has been around for awhile.
The second medication is Stattera which is mainly used to treat adult ADD (Attention Deficit Disorder). I don't have ADD but for me it helps me battle side effects of PTSD and Klonopin, so I can both concentrate on, and give a crap about, mundane things. Unfortunately this one is expensive.
The real key for me to function is Klonopin.

I don't know if this will help you. My brother, who also has PTSD, hated Klonopin. It didn't help him at all. He did better with Paxil. For me, Paxil is like taking pez. It does nothing except perhaps contribute to my already massive desire to sleep all the time.

So be warned! Drugs may mean inexpensive quick help sometimes for some people, but figuring out whether they help or hurt and what to take (if anything) can be an unpleasant, lab-rat-like experience.
