thanks.. were you open with your friends? how did you cope with other girls/ friends when you still dont have breast?? thats also one of my problems.. im really embarrassed..
is your weight too low maybe cos this can prevent your body maturing. i was considered a late bloomer at 15. if its not your weight then see your doctor, as it can give you further health problems. although my periods started when i was 15 i still didnt get breasts till nearly 20, now at 24 i am a 34dd. so it will come everyone is different. but 18 does seem a bit extreme see a doctor. however embarrasing it is see a doctor i know its not nice, but these things need to be done.
