First off, good job in getting through the surgery. As someone who is 35,and has had major surgery(gasterectomy, pancretectomy, splenectomy all emergency surgury at once) i understand what your going through. I suggest you acknowledge that you have some depression, and apprehension over your future. That's normal, i would be more worried if you didn't care. Your worring about something 10 years from now, but it seems that your really thinking about how crappy your life has been right now, and therefore self pity is coming up in the form of future worry. Thats normal, and its okay. Your going to have up and down days mentally, you will survive. My suggestions are simple: exercise helped me tremendously, even if i could only do five minutes of walking. It brought back my strength, my resolve, and the endorphins released helped me fight off the depression. It also made me hungrier, thus i ate more, and my energy level came back faster. When my energy returned to a more normal level, i began to change my thinking, i began to think" Hey this is a battle, and I'm going to win." I know it sounds corny but this is true: Warriors go to war, and you my friend are in for another battle. In addition to the exercise i stopped talking to people that stressed me out(its not an excuse to get rid of close friends that don't agree with the way you are, i mean the people you don't have time for because they weren't there for you, and probably won't be.) Good luck.
