Many have heard of these diseases, that often go together, but few know about them, and more and more have to deal with them. This, unfortunately, usually starts when you are a teenager, especially to those that lack self-confidence.
Depressions can have many causes.

Adolescence is marked by (bad) idols, (bad) media examples, examples which show models, stars with a so-called ‘perfect body’. A lot of teenagers want to have that ‘perfect body’ too, because of different reasons like: lack of self-confidence, the wish to be accepted by society, or even just the need to find a boyfriend, but most important, because they’re not happy with their body.
In this case anorexia and bulimia can occur and develop.

In the desire to loose weight many forget about their health and, maybe worse, they do not realize they need help, psychological help, because these diseases are not only physical, and can be, in extreme cases, lethal.

No one can say it is not nice to be slim, but this as long as your health is not affected. Perfect would be to keep trying to be content with your body as it is because, after all, happiness starts from self-respect.
