If you can talk to a parent or family member, let them know you are having difficulty and need to speak to someone.  There are mental health centers in nearly any town.  If you go to a church or temple, you can ask your clergyman.  It can also be very helpful to tell a teacher whom you trust, who should then put you in touch with your school counselor.  Sometimes you have to be brave enough just to choose the safest adult you can think of and let them know you need help.  We all need to reach out to someone at various points in our lives.\n\nBest wishes,\nToltex, Inc.');
