Money worries and generally fed up

So I’m on week 3 of radiology, had chemo last week and due another next week. I have a peg tube fitted ready for when I can’t swallow anymore and this morning eating toast was like eating razor blades - BUT what has really set me off today on a downward spiral is when the nutritionist came to show me how to reposition my feeding tube daily and we were having a general chit chat and I mentioned that I was trying to work a couple of hours at the weekend to try to get extra money in to be able to pay the bills this month and she was totally outraged and shocked that I was only being paid SSP - now I was pretty peed off beforehand that I work for a care company that doesn’t pay sick pay for anything, but she told me she has never met anyone that wasn’t being paid by their company for being off with cancer - I can’t claim any benefits as my husband works for just over minimum wage so we are above the threshold - anyway now I am in a dark dark miserable place - I no longer want to help the company by doing a couple of hours at the weekends when I’m not in hospital - they will pay me the hours I work but it’s only about 10 in total that I manage to do with what’s going on - and also I now don’t want to go back after all this is done - I want to go somewhere that will appreciate me more and this has just put a black mark on it all for me. How are you supposed to live on £116 per week - it costs that in petrol for the week travelling back and forth to treatments as the hospital I go to is 15 miles away !!  Sorry if this seems trivial but it’s really got my goat !!
