Terrified!!!

So i’ve been try since July now, & i finally got the courage to make a GYN apt which is on Feb 11th and i’m absolutely terrified. The only thing in this world i want is to be a mom, to have a baby. I’m so terrified i’ll be told i can’t conceive. I know it takes a long time for some people, as it took my mom 4years. Seeing as it’ll be my first time seeing this doctor, how should i go about bringing up TTC? I feel like i’ll be judged since i’m only 22. I have anxiety so i’m just kinda freaking out & would love tips. Thank you. 💓
