Same way you "get over" any trauma ... With counseling.
How do you get over trauma that was committed by your own older brother, who is 20 years old and comes home every month (for who-knows-what reason)?
Depends on what kind of trauma you went through.
Any trauma we go through is devastating. No one can tell us what we feel. It is however important that we work through it so that we can move on being happy and healthy in our own life. The bible tells us at Psalm 34:18 tells us: " Jehovah is close to the broken-hearted. He saves those who are crushed in spirit". Realizing that a relationship with God and daily prayer are essential to life and happiness has helped me to cope with trauma, perhaps it can do the same for you
