Sounds like you might have to cut back on a few things. Do you really need an upgraded phone? Or your gym membership? Or a new TV? I've had to cut back on a few things, & have surprisingly realised there are alot of things I'd buy that I used to waste money on, like heaps of food for example. I only buy what I need every few days now. It's amazing what you can do without when you have to, and still lead a comfortable life. I also scour op shops where you can sometimes get new stuff that people have given away, as they've had to suddenly move. Sites like Facebook & gumtree also have free stuff you can look for too, or at very reduced prices (and it's not always second hand).
As to an extra income, what about offering tutoring services? I do this but the money is not a regular income.
There are work at home options too that you can google. Offer gardening services, baby sitting, handy man sercices etc. You can create free websites, advertise on Facebook or go by word of mouth and the old fashioned flyers too.
