ugh do NOT listen to a BANK employee about credit!! her JOB is to earn interest for her company. her JOB is to loan people money, not to HELP them, to GET THEIR MONEY. her interests are NOT yours. she probably means well but she is not "trained" to look out for YOU.
you do NOT need a credit card. do not do not do not. spend $100 instead on Dave Ramsey's Financial Peace University. it will be life changing for you. you can also get his books and cd's on amazon or any other bookseller. trust me, it will open your eyes!
please do this. you are in such a delicate position - the next few months will make you or break you.
do your own research, figure out what will help YOU. don't listen to people whose job is to take peoples' money, do NOT listen to credit card companies. they are not looking out for you.
