Thinking About Coming Out More

Later this week I'm meeting with some of my friends, and I'm thinking about coming out to them. I'm fairly confident that they'll be supportive, as I know that at least two of them are extremely supportive of LGBT+ people and rights, but there's one person that I'm not 100% sure how they feel and I don't want to ruin our friendship or make our reunion awkward. Also, I'm a little worried that the word might spread and end up back at my school somehow (we all go to different schools) and I'm not sure if I'm ready to be out there yet.
