I feel weird?

I consumed brownies 2-3 months ago and now I'm really entering puberty. I often get anxiety attacks. I shake a lot. I have dispersonalization or disrealization, I don't know which. Sometimes when I concentrate I feel a bit high again and now I'm worried that it's because of the age. Luckily it was only a one-time and small consumption of brownies but I've heard that my symptoms could also be due to puberty. I also feel dizzy sometimes and I'm always worrying about it so much. What do you think? Going to the doctor isn't a solution!
