I am writing in regards to a friend who served in the US Army. His name is Miguel Alvarado.I've known Miguel all my life. He was a happy, outgoing person who made people laugh with his humor. I noticed a significant change in Miguel's personality when he returned from military service. He wouldn't laugh anymore and he usually isolate himself from friends and loved ones. He never wanted to talk about his experience in the military. As a friend, I believe Miguel may be going through a post traumatic distress disorder that may require immediate medical attention. I appreciate anything and everything you can do for my friend, Miguel.Thank you. Angie R Torres
