Is getting a college degree really worth it?

I have a Bachelor's degree in Applied Mathematical Sciences, 5 Microsoft Certifications and a few years of experience in Accounting, IT Network Support, and Microsoft Excel programming. But I am always denied employment because I am overqualified. I only went to college at 18 because my parents told me to go so I went and graduated at 23. Ever since I got my Bachelor's degree it has done nothing but cause so much grief and misery in my life. I wish I never went to college to begin with. I just want a JOB AND NOT A CAREER, but every employer thinks I am going to leave the position to become SOME BIG SHOT at another company and that is the last thing I want in my life. Could someone please give me advice.
