My son has had very bad luck lately, when will it get better?

My son was born on January 17, 1995. Since mid-January his luck has been very bad. His health has been so bad he had to leave school in January and it doesn't seem to have improved. In the last 2 weeks 2 of his friends have suddenly died for unknown reasons. He is being forced to move into a dorm room with 3 other roommates next week. In 2 more weeks his classmates - and support system will be leaving for 2 months but he has to stay behind. He can't come home until August because he is in the military and doesn't have any leave until then. When will things get better for him?
