update!!
i took my car to different auto parts store and they told me again that my battery was bad but also that my alternator had a bad electrode(or something like that) and it also needed to be replace. they said that while my alternator was going bad it caused my battery to go bad as well. i went ahead and bought an alternator and will replace tomorrow.. after that i will see if my battery really needs to be replaced or if it will recharge.. i may replace my battery cables while im doing everything else(does anyone know if replacing the battery cables is very hard)??
THANKS!!
