Hi everyone!

So I'm sure that you all have heard this before a million times, but I just wanted to give my perspective and be fully interactive with what you guys suggest and hopefully you can all help me a lot because I'm really struggling with how to go about coming out at my particular workplace. So thank you for taking the time to help me out and sorry if it seems repetitive at all.
Primarily I'm a college student, but I work about 30 hours a work to pay for rent, food, books, etc, so quitting is not an option for me. I work for a company that I've been with about 6 months(So relatively short), but in that span I've made significant progress with the company and I'm the main trainer for new hires now. I really like everyone that I work with and I've even made a couple friends."Coming out" to my workplace really stresses me out because I'm in a position that requires me to be trusted by my fellow co-workers in order to move up in the company which would be ideal and could happen as soon as 3 months from now. There are several people who I know wouldn't have an issue with my transition, but at the same time, there are several that I'm confident would have an issue of some kind with it. As of now only 1 person knows that I confided in and she told me that she would be happy to help me tell others about it. So overall, I'm afraid that when I "come out" to everyone at work, it will be extremely weird and all of those relationships I've built will be diminished as well.
So what would you all recommend doing? I prefer telling people in a 1v1 setting, but my friend/coworker suggested telling everyone at once, so I wanted to get other opinions on it. I really want to continue working here because it has been going extremely well with my school schedule and just in general as well. All feedback is appreciated immensely, no matter how small you might think it is because I'm pretty scared to tell them. What I don't want to do is just procrastinate so much and people start to get suspicious. Again, thank you everyone for helping, it really does mean a lot, I'd be screwed without you all.
