Other things... we try not to toss out food. Stale bread=breadcrumbs. Meat bones and veg peels=soup broth. (Most vegs we eat peel-on anyway.) I sometimes do home made preserves, but honestly don't always have the energy for it... but one yummy basic one is apple jelly, which can be made from apple peels and cores.
Repair stuff, and have some fun with it. Creative mending can be a way of making clothes unique at the same time as keeping them in use. Buy secondhand when you need something, or better still, look for "freebies" on sites like Facebook Marketplace. BUT don't get things you don't need and/or love. (And if it's out of love... do you have space, or can you make space by getting rid of something you don't love?)
Find your fun in a way that fits your budget. There's plenty of crafts and art activities that can make use of discards. Anything from patchwork to pallet wood furniture. Find interesting public places to walk or jog or make use of an obstacle course, get a cheap or free bike. Team sports might be tricker if you need to join a club... so balance the benefit against the cost. It may be well worth it for you.
And also ask what supports your wellbeing. To some degree, that is a financial question, because it's downright stressful having an unpaid bill hanging over your head, or an empty pantry. But a lot of what really makes us feel happy or secure is less tied to money than we think. Somehow, find time for those things. Hanging out with friends, watching the stars, listening to the birds...
