hi mel,
it's norm to have such feeling.. i used to hv tat few mths back and really broke down.
it was so bad that i wld cry on and off and even hv nitemares.
my family and FH r very supportive and help me pull thru it..
if need to, do seek conselling.
most impt is to let ur FH know ur feeling and thots. a gd FH wld be able to listen to u and help u to overcome ur fear of getting married.
all the best and hope u wld hv the confidence to get married.
stay happy and be a beautiful bride ya..
