Doctors use antidepressant medications to treat PTSD -- and to control the feelings of anxiety and its associated symptoms -- including selective serotonin reuptake inhibitors (SSRIs) such as Paxil , Celexa , Luvox , Prozac , and Zoloft ; and tricyclic antidepressants such as Elavil and Doxepin . Tranquilizers such as Ativan and Klonopin ; mood stabilizers such as Depakote and Lamictal ; and neuroleptics such as Seroquel and Abilify are sometimes used. Certain blood pressure medicines are also sometimes used to control particular symptoms. For example prazosin may be used for nightmares, or propranolol may be used to help minimize the formation of traumatic memories.
There is evidence that susceptibility to PTSD is hereditary . Approximately 30% of the variance in PTSD is caused from genetics alone. For twin pairs exposed to combat in Vietnam, having a monozygotic (identical) twin with PTSD was associated with an increased risk of the co-twin's having PTSD compared to twins that were dizygotic (non-identical twins).  There is evidence that those with a genetically smaller hippocampus are more likely to develop PTSD following a traumatic event. Research has also found that PTSD shares many genetic influences common to other psychiatric disorders. Panic and generalized anxiety disorders and PTSD share 60% of the same genetic variance. Alcohol, nicotine, and drug dependence share greater than 40% genetic similarities. 
A. The prolonged (chronic) negative stress resulting from bullying has lead to threat of loss of job, career, health, livelihood, often also resulting in threat to marriage and family life. The family are the unseen victims of bullying.
of the key symptoms of prolonged negative stress is reactive depression; this causes the balance of the mind to be disturbed, leading first to thoughts of, then attempts at, and ultimately, suicide.
target of bullying may be unaware that they are being bullied, and even when they do realise (there's usually a moment of enlightenment as the person realises that the criticisms and tactics of control etc are invalid), they often cannot bring themselves to believe they are dealing with a disordered personality who lacks a conscience and does not share the same moral values as themselves. Naivety is the great enemy. The target of bullying is bewildered, confused, frightened, angry - and after enlightenment, very angry. For an answer to the question Why me? click here .
