Hi Clover,
Welcome to the forum and I second what sevena said about it being a huge step in itself, I hope this forum helps you to see that you aren't alone at all and we're here with you on this journey too.
I am 22 now but I was in a very similar situation when I was your age, I didn't smile, my teeth really hurt and I knew they weren't great but I actually managed to put them to the back of my mind until very recently, when thanks to this forum, I bit the bullet and I started my dental journey. This makes me want to reach out and hug you and tell you that it will be okay, I totally get the age thing and feeling like everyone else's teeth are so much whiter and stuff. My teeth are far from perfect (particularly my back molars), and I will most likely need an extraction of my upper back molar soon due to decay but I got there just in time, you're still young so your chances are better for that too.
I know it's easier said than done (I should take my own advice aha!) but you really needn't be embarrassed, you'd be surprised how many people are in a similar boat to yourself, even just by looking on this forum. In fact, I think it's good that you're trying to get in the mindset now at 16, even though it scares you. That is a very mature and admirable thing to do and there is always hope at any age.
Another thing... everyone's situation is different, some people neglect their teeth because of mental health, some people have bad accidents which knock their teeth out and some people are just born with bad genes that make them more prone to problems.
Everyone's different but the things that I've found helpful for me:
1) Finding a dentist that I trusted- I found my first expensive but phobic friendly one through a friend to ween myself in slowly, and then an NHS on the recommendation page on here which is looking as equally promising. (I'm not sure where you are sorry but recommendations and reviews are always good for building trust and getting the right place for you). You might not find the right place first, but there's no reason why you can't keep on trying.
2) Trying to work out what it is exactly that scares you- Pain, Judgement, the cost, needles, tooth loss
3) Trying to find strategies to make these fears easier and work these through with your dentist- like finding a dentist that offers painless injections, won't pass any judgement, will stop when asked, explains everything/just gets on with things and doesn't tell you.
4) Trying to change how I frame the whole experience by thinking about the outcome- what would be your ideal end goal? Confidence, better health, knowing that you kicked bum doing something that really scared you etc- Once you face a massive fear, I think it is true that other things get easier.
5) Get the ball rolling- I know making that first appointment is really scary but once you've started, you're one step closer to getting a healthier mouth. (I've also found getting early appointments reallly helpful as I'm always half asleep in the morning haha, by the time I'm properly awake I'm already home and have less time to panic). Maybe there is a time of day that works better for you?
6) Be kind and forgive yourself - This is a huge one! I think it's important to acknowledge that getting your teeth looked at is an act of self-care and you deserve to be happy and healthy. Maybe you could treat yourself after every little baby step you do? Like a walk in the park, new clothes, watch a film. I get to watch a film I know my boyfriend hates after every appointment, it's almost worth it to watch him squirm haha.
I really hope that you both feel able to and have family or friends that you can talk to about your feelings, I know it can feel like you are alone but as I said before a fear of the dentist and teeth problems is much more widespread than most people talk about. You might even help someone else out by opening up.
Keep us updated. Please feel free to either reply on here or drop me a private message if you wish, I'd be happy to listen if you just need to rant or want to know anything else about my journey so far.
Good luck.
