At that point, I had to go through a lot of insecurities which made me withdraw from food, I often didn’t eat for days and I ended up in the hospital multiple times which made me have to change schools to be closer to my home.

Thats a very dangerous road for a young girl and I'm glad to hear it was just a phase. It's all about balance and eating the right foods, not stopping eating altogether.

I would furthermore add that you should try your best to avoid processed foods and if possible, eat more fresh meals, also not forgetting to take supplements when needed.

Agreed. Processed foods are definitely the enemy and more meat, fish, vegetables, fruit is the key. Fatty foods are allowed to, but in moderation.
