Hello, 
I have been struggling a lot with stress for almost all my life and it is becoming harder with highschool. Sometimes im so scared and stress about school that i cry before taking the train. I constanly overthink about everything and i feel like in a constant state of worrying. Sometimes when i stress much my heatr starts beating very fast and i struggle to breathe like if my head was in a plastic bag. I have been doing a lot lf research about generalized anxiety and i think that i might have it. I will probably go to a psycologist soon but the thing is that im scared that i never had anything and that my parents will thinks im faking it or whatever. And i really wanted to keep that to myself but it became hard and now i really want to die and i feel very depressed.

Do you think i should see a doctor is it just normal ?
(sorry if my sentences sound weird, english is not my first language ?)
