Anorexia is an eating disorder that can have serious consequences if not treated in time.
It’s necessary to turn to professionals and specialized centers, without being ashamed of needing help. The sufferer has in him/herself everything he/she needs to heal: it is necessary to want it strongly, to have great will power, much motivation and a lot of patience.
