Please give me advice

Hey, so I'm 17 and in high school. I've told my best friends and family that I'm gay at the end of last year, I haven't told anyone at my school however because you know, jokes, a reputation, people who are going to ignore you ect. I have some "friends" but I changed to this school a year ago so I don't have real good friends. I'm just afraid that nobody will like me anymore but I'm also eager to tell them because I don't feel like I'm being myself around them. Please give me some advice what to do. Thanks -a 17 y/o guy
