Hi OP
You will be fine! I reduced my hours right down for the same reason, so I know it can be hard, but it’s taught me to budget better.
Get onto the money expert forums for some tips.
Most savings websites recommend getting a second account for bills/food and make sure to actively manage your money.
Also, make a budget, listing everything you spend and make it realistic. Don’t put £80 on food if in fact you spend £100 once you’ve added on extra trips to the shop/takeout.
Once you know what you spend on, review it and see what you could cut back on.
You need to have savings, so get any debt cleared ASAP and get saving!
Make the most of lockdown to save on expensive trips out. Always make your own lunch/picnics and cut back on treats. This is a great time to stop spending on clothes etc. Buy whatever you can second hand and sell stuff on eBay.
A friend of mine has always done this and despite a low income, she has loads of savings.
Saving can become as addictive as spending, so try and get into that mindset. If you have savings, the pressure of financial worries will be less.
There will be tons of things you can’t always budget for, like replacing phones/white goods, kids school shoes, mot etc. So this is where your savings help.
Maybe take a spending detox for one month and see how much you can save by not buying any non-essentials. I did this for three months and is was amazing how much I saved.
Clear your direct debits too, and spend your spare time searching for better deals on phones, gas, electric etc.
Even if you don’t do all this, you already know you can manage on the lower salary, so try not to let it become a stress for you. The reason you’re cutting back is to relieve job stress, so try not to become anxious about this.
