Open Question: Sudden side effects after a zoloft dosage increase?

I am 16 years old. 120 lbs. Three weeks ago, my Zoloft dosage from 100mgs to 150mgs. I have been considering since those side effects: anxiety and / or panic what seems like a pole when walking heart rate (up to 150 foot in sports) I feel nervous and uneasy, and sometimes I saw the inside of the side effects of Zoloft. Originally, I should be reported to them, my doctor. I do tomorrow. Can anyone help me figure out how this is going on? Panic is taking place several times a day now. I really need help.
