You could try networks, stiitstacs, hardware. Not all programming is as bad as what you play with in CS, from what I have been told. My degrees are in Networking and Information Technology. Cheer up EE have it much worse. I know not much comfort its like telling someone being stabbed that being shot is worse, both are fatal. What about the programming don't you like ? What got you interested in computers in the first place ? What do you still like about computers now ? Also, I recommend a break, travel a little bit, either road trip or plane or something just to clear your head. Take the summer off, just a week and head to a beach and do nothing or take an inexpensive backpacking trip and see the outdoors and smell fresh air you have been stuck inside too long. Also, try volunteering its good for the heart and head to help others. Yip, I know a suggest it a lot, but it does do good. There are so many people out there afraid of computers that it makes me proud when I help someone at my college/university overcome there fear of computers. Now for people that have a general dislike of them well I can never do anything with that.However, I agree programming is not my cup of tea either. Good luck and try some other classes like art, or exercise and get out and breath you will be alright. Was this answer helpful?
