I need some advice

Should I just post "I'm gay" on my snapchat story? I'm done with waiting for it to come up in conversation and I can't tell aby of my friends irl because I'm on a football trip for the rest of the day and we have a 3 day weekend because of Labor Day and I really don't want to want that long. I could text some of my friends but I'm not super close with any of my friends except for one that I'm kinda close with. Any advice is appreciated, thanks.
