     After successfully serving their term for 4 years, military service men and women are given the choice

to stay in the military or return to civilian life.

     For some, having to readjust to civilian life is one of the most challenging assignments our returning

soldiers and marines(水兵)will ever to undertake. While people may think readjusting should be simple,

they must take into consideration all physical and mental stress our servicemen went through.

     Post-traumatic Stress Disorder(创伤后应急障碍),or PTSD, is a mental disorder that can occur

following the experience or witnessing of life-threatening events such as military combat(打仗).

     Most survivors of trauma return to normal given a little time. In the military, the marines are given a

two-week course on how to return to civilian life.

     Unfortunately, some will have stress reactions that do not go away on their own, or may even get

worse over time. These individual may develop PTSD.

     People who suffer from PTSD have difficulty sleeping because they are often reliving the experience

through nightmares(梦魇)and flashbacks, and feel deserted or often stand off, and these symptoms can

be severe enough and last long enough to significantly damage the person's daily life.

     Fullerton College, like most colleges, has its own Veteran's(老兵)Office. Ray Bustos has been running

the office for 3 years. Bustos acts as a liaison(联络) for the school and the veteran students. He makes

sure the veterans returning to school get the right benefits. There are various types of financial aid for

soldiers and marines. He strongly encourages the use of the Veteran Affairs website.

     The website is very informative and extremely helpful for veterans as well as for friends and relatives

of veterans who want to learn more.
