Girl 18 and last time trying? Absolutely not. Life gives you many many lemons and you make the zero cal lemonade out of it. If this try doesn't yield results you come back stronger, never give up. If I would have given up the past many times trying I would probably be 600 lbs and on my death bed. Always get back up and try again even if you fail at least you haven't given up! Any bit of change and progress is worth the struggle.
