Brightsunset you escaped an abusive childhood and a marriage to a controlling angry man. You are amazing. Please do not beat yourself up.
Make a plan of how you can do a few things and then take it one step at a time.
As far as bills being paid can you set up some things with the bank, get them to help you?
Register with job centre and make sure you are getting any benefits due to you while you job hunt.
If things break, consider how serious it is, if it is 'this thing will kill me if not fixed' get it fixed professional or buy a new one (kettle toaster etc) if it is just this picture has fallen off the wall and is now propped on my sideboard - fine.
Buy food, I love buying food that is on special offer, eat within date or freeze, I love ready meals, I love easy easy pasta meals and salads that don't require much effort, I love tinned fish like mackerel in nice sauces, I love bagels and cream cheese. Find what you love, eat what you like. It's daunting but also exciting.
Well done. Good luck The hard bit is over, you are free, this is your me time, it won't be easy, but you can go to bed when you like, watch what TV you like, tell yourself GOOD, KIND messages about yourself. Google positive thinking and tell yourself often how fucking amazing you are.
