BB, I havn't had this issue (yet), but I hope I can say words that encourage somewhat. My dentist and hygenist have told me that all people in the movie industry have artificial, teeth that improve their appearance (movie star teeth). Many young people I know have had all or some of their teeth capped and have artificial teeth, in order to improve their appearance. The reason for saying this is that I hope the outcome will make you feel happy about the look and feel of your new teeth.
I also know what you mean by having a hard time coping, I've had many of those times myself. The only thing I can say about that is being around people who care about you and support you in whatever way they can. Time makes the biggest difference of all, this will be behind you one day soon.
We on this forum are so used to you supporting us in our everyday lives, with what matters to us, I hope you can find some comfort in knowing we are here to support you now.
