If you have never tried anything and don't know if anyone in your family has success with a medicine for a similar problem, I might start with sertraline (zoloft) since this can treat panic and PTSD. It will take up to 4 weeks for the full effect and is not an addictive medicine.
If you don't have a history of addiction in you or your family medicines like lorazepam or clonazepam will bring more immediately relief...but use with extreme caution.
Double check with your doctor to make sure it will be safe for you. Let me know if you need more help.
