I came out a year ago. I'm a 9th grader. I thought naturally people would most likely be immature about it in my grade level but people were cool about it. I didn't lose any friends but people were taking time to get used to it but it didn't take very long. Nobody treats me differently.
The sooner you get it over with the faster people will adjust. [Before I came out,] people suspected me and I always told them no. They forgave me. They kinda understood.
