I've started to look at everything I can do extra that helps. I worked out that the I crease in my utility bill is an extra 3.30 a day. So I aim to make that a day. This has really helped mentally worrying as you describe.
So firstly I complete surveys for an hour day while watching telly, I usually make at least a tenner a week. You can use my link here if you want to try it and you get 40p to start you off with.
I'm inviting you to join AttaPoll. Get paid to take surveys. Download the app here: attapoll.app/join/skawm
The other app I use is Airtime Rewards which you register your cards with and then any time you use one of their preferred retailers eg boots, you get a little cashback. You can only use the cashback off your mobile phone bill but I have been able to discount my mobile bill by a tenner a month since I started using it. This is my referral code that you put in the promotions section which gives you a pound boost.
Do you want to reduce your phone bill?
Download Airtime Rewards for free with my code KAVJXMCJ and save money off your phone bill every time you shop with brands like Boots, Greggs, Wilko, Argos and loads more: airtimerewards.app.link/PTcbZ52Ptob
The other thing I would recommend is to make sure you are signed up to cashback sites, I use quidco. Do all your online shopping via this and collect cashback, but also each year renew your various insurances through it to make 100s. For example, I just compared and changed pet insurance provider and got 70 cashback. It takes ages to clear, so I save it all for Xmas. Make around 400 a year.
You can use this referral code and it gives you a 5 pounds boost when your first 5 pounds cashback clears.

This is over 1000 extra a year for relatively little effort and usual spending. Hope it helps x
