I'm going to come out to my family even though my mom doesn't want me to.
Why do you feel you need to come out?
I'm tired of keeping the secret to myself, I want to be free.
I'm sorry your mom isn't being supportive during this time. If coming out to your family will give you some peace of mind, you should definitely go for it. Your mom may be upset for a while, but if she's truly supportive, she will understand.
My mom doesn't want me to come out to the rest of my family because she doesn't support me. She was mad when I told her.
If being in the closet is hard for you, then you need to be honest with yourself and others. If coming out will harm you, then you should keep it to yourself.
