Coming out to parents

Might not be the answer you’re looking for, but remember that you don’t have to come out. If you’re scared that they will see you differently, don’t come out. At the end of the day, your you and your identity will only be most important to you. It may seem like a big deal, but to most others it isn’t. It shouldn’t affect how you act or behave. In most situations it will be completely irrelevant information.
Don’t feel guilty about not coming out. That information is for you, and you choose who to share it with. Also, don’t rush it. Media puts a lot of pressure around the coming out moment, and makes it seem like you have to tell literally everyone, and they miss out the fact that you can just live with your identity and be happy and not have to share it instantly. I’m bi, I’ve known for the past eight years and I’ve never officially told anyone I’m bi. I’m not hiding it either. Those who I care about just know from the fact that I’ve just talked about liking both guys and girls.
If you have hesitation about coming out to your parents because you suspect they may be homo/transphobic, don’t come out. Especially if you’re young/still at school/living with them. It’s better to keep that info to yourself, and have their support in other things (like finances), and have a calm home environment.
Your identity if for you, not others.
