After I told them, they yelled at me.
I am sorry to read that this happened to you. If your family is not supportive of you, this can be a huge challenge. Are you dependent on them in some way (financially, etc.)? This could affect choices you make at this point. Make sure you connect with a supportive community or people and organizations that are afforming of you and your identity. If you are unable to receive support from your family, you can lean on them if necessary. If you feel your family needs more information you can always refer them to appropriate websites and organizations that can help them to understand that this is natural and normal and learn the negative effects of non-affirming people in the life of LGBTQ+ individuals.
