Sounds like you're on a bit of overload at the moment.
Since you wrote your post you'll have had another round of chemo....over halfway and counting.
You have done really well till now but it sounds like you need a bit of support. I hope you can get it from this group if from nowhere else.
I see you say that you're working part time as well as looking after your husband and 6 year old. Have you checked to see if you are eligible for any other form of financial support? (I don't know your annual income-and don't want to! LOL)
take care of yourself Sending hugs
