One concept- the "Spoon Theory"- is a very popular analogy to help able-bodied people begin to understand some of the limitations that chronically ill people face. Open Letter To Those Without An Invisible Disability Or Chronic Illness is another blog post written to help well-meaning people understand what life with a chronic illness (especially an "invisible" one) can be like. This is another similar piece Pay no attention to the girl behind the smile -what I wish people knew about me.
Several articles ran recently In Psychology Today about things that people who live with chronic illness want to hear or don't want to hear:
What Those with Chronic Pain or Illness Don't Want to Hear You Say
What Those with Chronic Pain or Illness DO Want to Hear You Say
I think able-bodied friends and relatives so often want to help and be supportive, but simply don't know what to say or how to help. This is not something that our culture (here in the US) prepares us for. People often try to talk us out of our feelings ("come on, it's not that bad" or "look on the bright side" or "so and so has it worse than you do, you should feel lucky") or offer advice without asking first if we want to hear it. We know that this comes from a place of wanting to help, wanting to see us healthy again, etc, but it can get very hard to take. Above all, what we want is for people to see us how we are, to take the time to listen to how things really are for us (without offering unsolicited advice or judgement), not to assume that because we look okay we must feel better at the moment, to realize that when people see us we're at our best because at our worst we can't go out, and for people to make the effort to accommodate us when possible.
The one example of "what not to say" that seemed to cause confusion as part of a conversation recently, are the variations of "call me if you need anything" or "let me know if there's anything I can do". I know that I appreciate hearing that, and many people do, in the sense that the person genuinely wants to help out. However, the offer is so vague that it can really hard to know when or how to take them up on it. It puts the ball in our court, and honestly our court gets pretty overwhelming and we are likely to drop the ball. As the articles point out, specific offers or offers with parameters (such as "I'm in your neighborhood every Thursday afternoon, I'd be happy to run errands for you" or "I'm happy to bring you dinner from time to time"). It is very helpful for us to know what kind of help you have in mind, so we know what to feel comfortable asking for.
There is another reason why that question can lead to frustration. In some cases, it is a sincere offer to do something. In other cases, it is the person letting you know that they are not going to pay attention to your needs and that they expect you to speak up with them, every single time. For example, a friend used to invite me over and over to meet her at 9 AM across town. I can't drive, and I struggle to get up in the morning. There is no way this could work and this invitation made me feel really not "seen". There are times when I've explained that I need plans to be flexible, as I never know how I'm going to feel, and the person originally says they understand but then gets frustrated with me when I ask to change the plans. It's emotionally hard to not be able to do so many regular things, and relationships in which the ball is always in our court can be just too draining to maintain.
The frustrations that I've had are common and a lot of people have already written about them. I am including a list here of writings that explore the topics of giving advice, offering help, etc that can be helpful for us chronically ill people to read (sometimes we find solutions or validation in reading others' thoughts on the subject) as well as links to post or share if you want someone else to get the information:

This is written from the perspective of a parent of a child who has special needs, but what she has to say is just as applicable to people with chronic illness themselves. Many of us also do have children with various special needs so this post does double-duty.

It offers alternatives of things to say that would be more helpful and why these phrases, even if the speaker believes them to be true, may not help in a given situation.)
