You could study mechanical engineering.
Pretty much every field now has computer science baked into it. For example, you could work on Finite element modeling, CAD tools, simulation tools, software for testing, all kinds of specialized software tools for mechanical engineering are now complex enough to require hard core CS skills. Every good MechE department is going to have several researchers whose job is covertly 90% computer science. Imagine, for example, the work of figuring out how to run finite element simulation on a GPU card.
That said, if I were you, I’d wonder why I hate EE so much. Could it have just been a bad professor, or a bad class? did you hate beth digital and analog electronics? Did you get advanced enough to see filtering and systems on a chip, and wireless and FPGAs? As someone else said, mechatronjcs is a nice combo of electronics, software and mechanical.
