If symptoms are of anxiety
(fear, panic, tremor
, sweating, fast heart
, etc) and insomnia
then there are lots of treatments, including amitriptyline
. But best to focus on non-drug interventions for sleep
(see: http://goo.Gl/jcscx) and anxiety (see: http://goo.Gl/aibdp). If these fail, then there are very effective psychological treatments too. Good luck!
