Just to give background info I helped him get the job he was working when I got sick, gave him somewhere to stay when he was kicked out, helped get into the place we were staying in, and helped get the car he was driving. I never heard "I appreciate you." We both always said thank you so I didn't think anymore of it.

It sounds like you did everything you could to help the relationship. Obvious physical limitations prevented you from doing more. He should have some compassion toward you for that. He seems likes he's a controlling kind of guy, where he expects a woman to handle any responsibility, regardless if she's physically able. I think what you did was typical and normal.
But you asked the Q, "How do you show appreciation? I suppose by doing very simular things you did. You told him "thank you" for help he gave you. Sure, IF you're able, give him/her a massage. You cooked many meals. I'm sure you probably did the laundry. There's general house cleaning that's needed. To me, that's normal life for both the guy and the girl. How that work is divided is up to them. I try to remember to thank my wife for taking care of me, for all that she does a few times a week. I thank her for making a meal, doing laundry, for getting something from the store. In return, she never has to worry about her car, or that the house is clean, or that something always gets fixed, or get her favorite programs recorded for her. There are a number of things you can do - buy them their favorite snack, give them special time to watch TV and so on. I think you did it right, from what you wrote. I wouldn't feel guilty on your part.
