Hi I'm 15 and I'm a gay guy.
My friends know.
My teachers know
Everyone but my mother knows. She's a single mom who confronted me about my sexuality when married to her ex husband. He was mentally abusive and I was TERRIFFIED to admit it... So now I want to tell her, but don't know how :/ any suggestions how to tell your homophobic mother that you're a faggot?

Perhaps by having enough respect of yourself and other gays by not calling them faggots.

How about at 15, since you should really not be sexually anything, not worry about telling her.

So you are gay, it is what you are, and there is no need to announce it to anyone. You just are. Straight people don't go around telling everyone they are straight

I am a gay guy and the "you're a faggot" comment doesn't bother me at all, but it would offend a majority of the gay community.

What I tell others in your place is being gay is just a small part of who you are. You are a son, you are a student, you may be an athlete, you may be an avid movie watcher, you may be a singer, you may be a lot of things. So don't define yourself as gay and only gay.

Telling your mother is your decision to make. She has already suspected so it won't come as a total shock to her. Whether she accepts it is up to her and only her. You have no control over that. If you tell her in an upfront way and explain to her that you still love her and this changes nothing about y'alls relationship, it should go okay.
