Defo get an appointment witch citizens advice and let them know it’s a benefits claim
in the mean time get on to Facebook and find your community fridge and sign up and get the notifications. That is free food , doesn’t matter who you are , they are about stopping food heading to land fill.
Join Olio. , another place for free food. The major supermarkets in your area sign up and the reduced food is given away A few people so collect it and then advertise what that have and you pick up from there’s - it is all late evening, who knows what’s available, but worth keeping on top off
Then there is TooGoodToGo You do have to pay but you get rich pickings , esp if in your area supermarkets have signed up. Best deals are from the likes of -marks and Spencer’s service stations It’s an app but again there is a Fb page you can follow to see what people are getting.
if things are really tough , ask your GP practice for a food bank referral and say if it’s toiletries and cleaning products required. There’s not a Gp practice who is going to deny a request or send you on for a SW referral. , so don’t fear asking.
Just one food bank collection can make a huge difference. You are fed , there’s a bit of leeway
There is help , do not ever feel you can’t ask for it.
i wish you a more settled life Good luck xx
