How to deal with people trying to help

Hi, I’ve just read your profile, and I’m really sorry that you have been through a heck of a lot already. I have a feeling that you will get various replies to this one. My own view is that you set your own boundaries, without being rude or cutting potential help off completely. The reason why I say this is because in my final cycle of chemo, I was quite poorly and I did need a neighbours help a couple of times. It crept up unexpectedly and I was glad that I initially said something like - ‘that is so kind of you, but I am really lucky to have enough support at the moment. However, if things get worse, and I need more support, then I would call you, because I know you are reliable’. 
Im sure others will give other suggestions. Xx 

Thank you, I really appreciate your answer. You’re right I really don’t know what’s ahead of me and what help I might need. I’m also aware that people are just trying to be kind.

Hi, during chemo I am sure you'll want to be careful about your immune system, so this could be a reason to limit visitors and I'd hope people will understand this.  Just an idea that might give you a reason for politely posting back. Best wishes
