Parenting

I know that my entire life I have been told to appreciate my parents because some day the tables would turn and I would have to be there parent. I didn't think it would be so soon. I sit here and worry about them constantly. Are they eating healthy? Did they pay their bills?  Is it silly to be so worried for two perfectly capable adults... I'm only 22 years old. I should be out there having fun and making mistakes. Instead I am working 40 hours a week and living from Paycheck to Paycheck hoping that I can take care of myself and my family.
