Im Really scared tremors in my hands and Ect. Help!?

It may not be PD, since even with a family history it is rare to effect someone so young, however, it is a sign that something is going wrong, and likely in your brain. You need to see your doctor, he may send you to a neurologist. Do not put it off. Many things can be easily resolved if they aren't allowed to progress too far. The sooner you find out the likelier you are to get better. There are many things that can come across as tremors, from certain toxins to conditions like epilepsy or PD. It can also be a sign of nerve damage. Talk with your parents, get to a doctor.
