Arranged marriage - question for people who went through?

NJmasti,
I havent had any affair at all throughout my life, let alone it going bad. :) I am 23 years of age at present. The reason why i am saying i am not mentally prepared is because i am the youngest of 4 siblings. I have been pampered like anything throughout my life and maybe that is why i am pretty dependent on everyone to do everything for me. This may be the major reason why i am not mentally prepared to go for the marriage thing.
