TRYING TO TELL PARENTS😵

Brianna
I'm in dying need of help to tell my parents/ family I'm pregnant. I'm 18, still in school, and one of my older sisters got pregnant around 16,  so I know how upsetting it was when they found out on her. I know I need to. It I HONESTLY can not bring myself to do it. My boyfriend and I have been trying to figure a way to tell them and when but we just can't. I don't know what to do or even how to tell them. I need help or someone to just yell at me to do so, so I'm not being a big chicken on telling them. I know it will be hard but I also know they will accept it but be VERY disappointed that I am, I was the one they trusted and I am the one that let them down. So HELP
