I haven't been able to eat lately.. For about 2 or 3 months. I eat when I can, which is not very often.. Mostly I just nibble at things. I just don't want it, it's not like i'm doing it on purpose I just can't eat.. i don't even feel hungry very often. And recently I have started getting really painful headaches all the time. And I get dizzy and almost passout. I start getting really hot then my hearing starts going and Then everything gets blurry and I have to sit down or I'll passout. What is wrong with me? Why is this all happening to me? What can i do?
