Tips on where to cut back

I am about to enter a tight financial situation - my flatmate has moved out and I have been struggling to find a replacement. I will be paying full rent on my own which is 60% of my income until I can find someone. I am doing the best I can, multiple paid ads and actively contacting people.

In the meantime, any suggestions on where I can cut back would be appreciated. So far, I have cancelled a few subscriptions, my phone contract is nearly finished so I will drop down to a cheaper plan, and I have put up a few items for sale on Facebook marketplace.

Thanks in advance!
