To summarise, I'm a single parent of 6, ages 6 to 18. I'm widowed so no partner to call on and family not interested in helping (harsh but true). 18 year old has cancer (currently well and clear scans for a year, no current treatment). Had a panicky night imagining what would happen if I got ill with CV and had to go into hospital...Presumably friends couldn't help out due to infection risk?
