Lost enamel due to anxiety and upbringing

Hi! As per the heading, I am now looking for ways to help improved my teeth appearance. At the same time, I know lost enamel can’t be recovered so I am looking for ways to help improve it.

A bit of background story: I grew up with a mentally ill mother and my father spend most of the time at work so hardly anyone guide me on basic hygiene such as taking care of teeth. Along the teenage stages, I do have some anxiety, probably under the influence of my mother and some gaslighting and manipulative relatives. So that might cause me to neglect my own self care due to anxiety. It dampens me even more due to the lost of self esteem because of my look and teeth.

Now that I am older, I am wondering if there is a way to improve my teeth as I want to be able to smile brightly without worrying about my teeth appearance. Deep inside, I know I am someone who love to smiles but lost it all due to some toxic people during my upbringing.

Currently taking steps to improve it by seeking psychologist and now dental. Just graduated and started to look for a job and I want to take this chance to become someone I am supposed to be.

Any recommendations like whitening or bleaching or cosmetic for teeth improvement that can work? And if there is a recommended dental place.

Thank you so much in advance!
