Should I wait to come out to my parents; what if they don't believe me at my age?

If you’re confident in what you’re coming out as, I think it’s best to just get straight to the point. That is, if your parents not believing you is the worst-case scenario for you; then it’s always better than not telling them at all. That way, you can later prove them you were right the entire time!

It's a personal choice, coming out is something you can do whenever you feel ready and you believe it would make you feel good to openly be who you are. You can try to explain them in detail how you feel, so they'll have a better chance to understand you. Remember that coming out is something you do primarily for yourself, to feel better as you're finally feeling free to live your identity openly. Their rraction of course it's important, but you can work on it, in case it's not the one you want. But if they aren't LGBTphobic and they have trust in you, there's no reason why they shouldn't believe you!

You should strive to be honest to yourself and to your parents, and to be happy. It's hard to be happy if you feel you can't be yourself. I think it's always better to be happy than to suffer, even if it means losing someone you love.

If you feel comfortable and safe you should do what you feel you need to do inside. If you don’t feel comfortable and safe then it might be a good idea to speak with a friend or someone else you trust first.
