Hunny, please try not to worry.
i know its very much easier said than done but you will manage.
I am the main bread winner and to go on mat i lost £900 per month, 3 months after having Alice Adam was made redundant and spent 6 months on JSA, we are still here, we managed, we were a bit crazy with the CC and are now even worse of but we are still managing.
look at the things you can do.
EG payment breaks on loans/mortgages, we have a 6 month mat break atm or we would have no chance!
i changed my G&E to quarterly bills instead of DD as i knew we wouldnt have the funds in everymonth but would be able to juggle things to pay them.
there are lots of options hun, try not to panic
