If you're ever scared about coming out, let me give you some advice:

You have to know if you're ready. Don't tell people who may tell others. When you know for sure, and you're ready, come out of the closet.

Some people may accept you. Others may not. But that's life. There are always going to be a few people who don't want to understand because they live in a fixed mindset. But it depends on how you react to it. Stay strong, and hope that someday, you'll be surrounded by people who truly care and love you for who you are, not for your sexual preference.
