I really want to come out as agender and bisexual but I feel like have no courage. I even know that they will be accepting me but I still can't do it.
Don't be scared. If you truly know that you aren't heterosexual, go for it! It's such a mistake to try to hide from your family (if that's who you're talking about). After you have it in the open, conversations can flow smoothly without you censoring everything that comes out of your mouth. If people discriminate you because of your gender identity or sexual orientation, they're the ones that are wrong.
