I want to get help, but I don't want to hurt other, I don't want them to worry, & I don't know how I would tell my friends I have depression. They judge really quickly when someone has depression, they think they should be happy, & that it is werid people are depressed.

I don't know how to reach out. I always ask questions about getting help, but I never do because I am weakling & too scared.
I don't who I should tell, Should I tell my teacher? I don't want him to worry about me,and I don't know how to tell my teacher.
