for the back aches,,try using a heating
pad...And for the puking reflex just relax
and and try to eat light foods...And for
your father, if he is very understanding
just let him know that you need to speak
with him and that
you of all times need him to listen to you
with an open mind. And once you'v brought
yourself to talk to him it wont be so bad.
Your body is tense wich in turn will
cause ur body to ach and have the
reflexes. So your best shot is to work on
that.
