I was very afraid, so much I didn't consider (and maybe you neither) that it doesn't have to be an all-in event. You can come out person by person, or if there really is nobody you trust, reach out to other queer people, organizations or online communities. They will always be responsible with not outing you, because we've all been through this. Exchange with other queer people helped me a lot with accepting myself and just the joy of being among people who "get me".

I know the fear of losing friends and I don't know you, so it might be warranted, but hiding your true self to not lose friends is also a terrible pain you're afflicting to yourself.

I was afraid to tell my parents, but when I finally did they didn't react at all how I thought. They are pretty Christian and my dad always made gay jokes so I thought they'd disown me or something. Instead they took me out for ice cream.

The most important thing you need to consider is can you support your own life. If the answer is yes, coming out is much less risky because you can just move away and start a new life in a more liberal place.

Otherwise you need to consider more carefully.
