Big HUGS to you and partner , sounds to be pretty grim for you both right now
Me and DH exist on very very little money, but we still find fun things to do which cost either nothing or very little
Look up your nearest college that does hairdressing and beauty - get booked in there for a cut or colour or facial or manicure, just costs a few pounds
We are just back from a weekend break in Edinburgh, 3 nights including flights, £200. We used the too good to go app for lunches and you could even get a buffet breakfast from pretty good hotels for £3 on that. When we wanted a drink, Wetherspoons sorted that. We walked everywhere and saw everything that was free and we had a great time because it was a few days away from the drudgery of making ends meet ( it will be our only holiday this year )
Use the too good to go app to top up the shopping - esp if you live in a town or city ( its not good where I am cos Im rural but I always look at it when in a city )
We go to cinema on half price Tuesdays. Not every week but if there is a film we really want to see, then its half price Tuesday for us
Look at local FB pages to you to see whats happening and FREE and go along to whatever you can. Having a trip out really does help the mental wellbeing
Hopefully DH will find work soon and things will get easier for you. Yes its a bummer not being able to look ahead but those days will come around again. For now its finding things you can do that make life enjoyable or at least bearable for now
Best of luck xx
