Getting hit with weakness, shakes inside of me, I feel my brain doesn't send the correct message for me to move correctly. I'm 18 female?

Could it be Parkinson's? I believe no one in my family has or had it, but I'm scared I feel I move werid or not right at times I feel weak my brain doesn't even think right at times like I'm hallucinating. When I look at my hands they shake at times other times not that much or at all but I still feel it inside of me I'm on my iphone 24/7 I also have anxiety

It maybe you are paranoid and anxious; and the anxiety is causing the tremor in your hands.

Do not use your phone too much; it may lead to anxiety.

Please see a doctor or a therapist.
