I’ve suffered with bulimia for 9 years. It’s had a huge effect on my teeth and knocked my confidence massively

When I was 16 I developed bulimia, I’m now 25 and trying my best to not do it anymore but I still relapse. My back teeth have had to be removed, I still have my front teeth but they’re discoloured from the acid and have lost a lot of enamel. It’s having such a huge impact on my life, I wont leave my home but if I have to I won’t open my mouth or smile, I’m just devastated over what I’ve lost. I need some advice but I know to have cosmetic dentistry done the price is huge and money I don’t have
