I have a similar problem - i'm studying electrical engineering (currently in 3rd year) but i'm passionate about programming and web development. I recently wanted to switch to software engineering but i realized that switching will be a pain in the ass - i would be delay my graduation by at least 1.5 years + spend more money. Anyways, i decided that it wasn't really worth the changing majors at this point. Instead, i will be attending some software engineering lectures on campus and self teach.
