I need to tell somebody about what is happening right now and need advice?

Its normal to feel like the world is over whelming you as a teenager. Your right tho it isn't normal to want to cut yourself. I would seek help from whoever you can to help you get through this. I am sure your parents would rather know how you feel not rather then to have you do it and become seriously hurt. Just let them know you are coming to them because you have these urges and feel you need help before you actually act on this. I myself as a parent would be relived my child came to me and I would help in whatever way i possibly can. My niece is going through something similar and her mother is being very helpful and encouraging anything she can to help her. talk to your parents if you are as spoiled as you say you are they will help you and be understanding parents.
