Scared to go to the dentist

I seen someone else post on here about it but I can’t find it so I’ll make my own. I’m terrified of going to the dentist and need advice on calming myself.

I haven’t been in 5 years, the other day I counted 10 cavities, yes TEN! on my top teeth. I also have extra teeth growing in behind my other teeth in the bottom part of my mouth (my pediatric dentist knew about that though so I’m sure it’s in my files) and those teeth are starting to cause the teeth in front to like tilt, I don’t know how to explain it.

I’m just embarrassed to go, I don’t want them thinking I just don’t care about my teeth. I haven’t had insurance and couldn’t afford to go with just cash.

My entire mouth is a mess. I keep telling myself that they’ve probably seen much worse but I feel like my mouth is the worst ever.😶
