Oh well, how are you coping with it and do you have any other things like anxiety or depression
I'm either pansexual or polysexual at this point, and I'm too busy to figure out which at the moment. My advice to coming out, regardless of your sexuality or gender identity, is to approach the softest parent first. For me, my softest parent was my mother. Make sure to approach the parent alone and just inquire about how they view the community in general, and if they question you either 1) come out to the parent right then and there, or 2) cover for yourself saying you heard or saw something on the news related to the community. Then do this again but with the harder parent.
Once you figure out their stances on the community, you can determine if it is safe for you to come out. If they seemed iffy on it, wait a bit but keep up a small pressure of the occasional news bit from the community. If they seemed supportive, take some time to sit them down and tell them. If they seemed against it, be wary, and if you feel unsafe talking about the matter again, I suggest you stay in the closet to them, no matter how much it hurts.
I also have an anxiety disorder and depression so if you need tips or coping mechanisms just ask away.
