Finally made the appointment

I’m so nervous I haven’t seen a dentist in very long (10 years) I’m 33 female and my gums and teeth are soo bad. Cracked broken and receded. I emailed a place nearby and told them my story. And they emailed me back with some comfort. And we set the appointment. Will I show up? I sure hope I don’t back down. I just want a nice normal smile, I don’t want to hit my 40s still living like this 😢
