I need advice I haven’t been eating ❤️

I’m 15 and have a history of anxiety and depression. I have to get this out of my system and I’m sorry, I had sandwiches for school every day and I hated them I would never eat at all at lunchtime. When I was in year 7 I had a lot of stuffed animals in my wardrobe, and I would come home from school and hide the food in my wardrobe under the stuffed animals. I did it for a whole year and obviously it got mouldy after being in there for a whole year, I finally cracked and told my parents one night and couldn’t stop crying it was awful I’ve never felt so depressed in my life
