If the strong emotions that began when your parents first split up last for a long time, and are really getting in the way of the normal things you do in your life, ask for help.
Feeling depressed, having trouble managing your anger, feeling extremely anxious, thinking about hurting yourself or escaping, or just feeling out of control are all situations that you can and should get help for.
Tell your parents, teacher, counselor or another adult you trust that you want to talk to someone who can help you, And if you aren't getting the help you think you need, keep asking until you get it.
