Mic80. I see this as a time when you need to be as stress free as possible. It's all about you, dealing with your treatment, getting through it and returning to your usual self. You are the important one and it takes all of our physical and more so, mental strength getting through it. It's a waste of energy feeling bad about letting others down. You need that energy for you. It's not for a long time, and you need to come out of it, the best you can. It's very ok to say no, when that's all you want to say. Thoughtful people will totally understand, and those that don't aren't walking in your shoes. Rest rest rest when needed, do what you can when you are able and have balance in your life without pressure. You are responsible for you. It's all about getting through it as best you can. You can do it.
