I'm a 22 undergrad struggling with a major I'm very passionate about, should I change it?

I’m a 22yo with about 1.5–2 years worth of college credits as an Info Tech major. I failed Accounting I once and Macroeconomics twice mostly because I only skimmed the book, had less than stellar professors and I accidentally missed the final exam. I’ve taken breaks in school and I’m getting old for a student with so little credits and I’m afraid if I change my major I may prolong my education (and student loans).

When things weren’t going so well at my previous college and my advisor suggested I change majors I decided it was time to transfer to another school. Now I was at some level struggling with my major at my old school and if I were to continue I’d probably have to take Macroeconomics for a 3rd time (I almost passed it the 2nd time but missed the final). I have always been very passionate about computers and how they work and I can’t really see myself studying anything else but if Info Tech is causing me to struggle at this point and the courses only get more difficult I’m beginning to think maybe it isn’t the major for me. As passionate as I am about Info Tech I’m even more passionate about receiving my college degree, no matter what the major. If I drop out it will be the biggest failure of my life and it will define me. I’ve looked into other majors briefly and Political Science or Communication Studies both interest me but I’m open to others. What I really need is a major I enjoy but is also easier than Info Tech. If I could continue Info Tech without the “filler” difficult courses that have nothing to do with computers and technology that would be ideal but I don’t think that option is available.
