Telling parents

Is anybody else terrified of telling your parents for whatever reason? Even if you are plenty old enough? Lol I am so scared. But I am 27 years old and in a committed relationship. I just know it’s not what they want for me right now so I am being a huge wuss about telling them. But I’m getting to the point now at almost 9 weeks that I just want them to know so I can talk about it and not have to keep having this “secret.” I feel silly but I know others have to of felt this way. I need advice!
