I'm not sure if you are in the US, but if you are apply for unemployment and apply now. The sooner you do it the longer your savings will last. And having gone through this before, you need to cut spending to the bone. Beyond not going out to eat since that is handled, but see if you can reduce your car insurance, drop online recurring services, etc.
Before you cut everything, keep in mind that you're still a human being and have psychological needs. If that streaming service brings you hours of joy, it might be cheaper to keep it than the bills for your mental health treatment down the line.
Don't just cut everything out of your life cold turkey. Keep something that brings you joy.
Having just basic internet and youtube can go a long way. So you can get creative during a crisis and learn to work with a bit less to get almost as much.
There are also a few free services. A lot of them (IMDB tv, tubi, etc) show alot of the same movies and shows, but Pluto TV is actually a very interesting service (features content from Viacom and "clip shows" from networks like CNN)
You can stream most movies and TV shows online for free if you are willing to spend the time looking for them!
Friendly reminder that there is nothing immoral about "piracy" of digital content. Culture should be free, so if you're not in a position to afford content, don't pay for it.
In many cities Comcast and other ISPs are offering free or reduced internet plans - might be worth looking into. And with the libraries closed your point is valid, you do need some outlets.
Kanopy if your library offers it. Free streaming service, no ads. Lots of good stuff. Depending on one's tastes it might be better than Netflix—some major movies rotate through, lots of classics, quite a few Criterion movies at any given time. Surprisingly poor on the childrens' entertainment front, but that's what PBS is for.
May not apply to you, but if you're an Xfinity customer, their mobile service is a great value: runs on the Verizon network, and you only pay for data. I switched to it for a few months during a financial crisis I had. It wasn't good for tethering (that gets too expensive vs. a carrier like Verizon), but there were months my bill was only $12 or $24 due to minimal data use (I brought my iPhone from Verizon)
I was using Verizon on a 2 GiB shared plan with my wife. Neither of us use much data, so we always had plenty left over. Switched to Spectrum, which is also on Verizon. It requires Spectrum internet or TV. The bill dropped from about $80 fo the two of us to $28. The new plan is $14 per phone per gig, data is shared. The price includes all taxes. The only extra charges are for international calls or adding another gig.
Tracfone can be slightly cheaper, especially for light users. I’m on their cheapest smartphone plan at $10/month/phone. (You have to buy a year ahead to get this rate, but you can get to $12 with a two month purchase).
They work on the TMobile, Verizon and AT&T network, and you can bring your own unlocked phone.
Millions of people are filing for unemployment right now. Do this first. Like, reasearch over the weekend and get to filing first thing Monday morning.
