Hey... Leticia... I believe this is your first post here on PC. So... to PsychCentral! Oh... & by the way... we're not "putting up with you". This is what we're all here for!

Unfortunately, we here on PC cannot diagnose you. In order to really find out if you are developing an eating disorder, you'll need to see a mental health professional... ideally at an eating disorders program... or perhaps a therapist who is experienced in working with individuals who have eating-related concerns. I see you live in Brazil. So I don't know what kinds of services are available to you where you are.

Whether or not you could actually be diagnosed as having an eating disorder, you clearly have some things going on that are of concern to you. So, under any circumstances, it seems to me consulting a counselor, a therapist or other mental health professional would make sense if for no other reason than to put your fears to rest. I wish you well...
