Fantastic Patty,
It's always good when motivated people are not afraid to express themselves here.  Good inspiration for everybody !
Those last 13-15 pounds are usually the harder ones.  (I'm in my last 13 pounds now, lol !)  I'm sure with regular exercise  and dieting you should reach your goal though.  It is a lot easier to lose weight when you work out regularly, no doubt about that.   20 minutes a day, 6 days per week ... you'll be melting in no time.
Cheers !
Marc
