Cannot receive sickness or injury, shoubyouteate(傷病手当) benefit money. Please help

TLDR : I am too unwell to work and only found out today that I cannot receive health insurance benefit money from my precious company’s insurance provider.
I found [this place](https://www.fr-kenpo.or.jp/eng/member/application/retire_b.html) and[ this place](https://www.hp-kenpo.or.jp/eng/member/outline/retire_a.html) but they require you to apply within 20 days of losing previous insurance. Don’t know what to do, will probably end up homeless.

Long version. I worked at a company for a year before being fired because I was too sick to work, luckily because of a benefit they had I was able to continually get health insurance income each month, though it was only 17man. After a couple of months I was feeling a bit better and tried to work out of a contracting company, unfortunately I started falling over, fainting etc while at work and 3 months later they just told me not to come back. I was still within the contract of the contracting company but because I was sick they couldn’t put me in a job. During this time I was receiving health insurance money.

My contract ended with them at the end of January. The[ insurance company they were with](https://www.kyoukaikenpo.or.jp/) only accepts shoubyouteate after the payment date of the time not worked, which is a month later. I asked the company what I should do to continue to obtain shoubyouteate money and they said to go to hello work.
Hello work told me to “Come back when I am able to work”, I asked about the monthly health insurance and they told me to go to the city office and ask them. No one knew, no one at Hello Work, no one at the city office. The Health Insurance Department at the city office only deals with handing out health insurance cards, not anything to do with shoubyouteate. So they told me to go back and contact my company, which I did, who told me to then go to hello work again and they told me to wait for something in the mail, which I did, and it was for some kind of school program or something weird. Not anything to do with shoubyouteate. Eventually a friend searched around for me and found the exact [same insurance company](https://www.kyoukaikenpo.or.jp/) my previous company was using.(BTW I asked my friend if there were any other companies, she got a bit mad at me and said she found the only one.. my mistake, I should have looked myself but I assumed all these institutions and companies would point me in the right direction.) . My friend said I can send an application to this place. I read over the website and filled out the forms, went to the doctor and had them fill out the shoubyouteate. I had some questions about the forms so I emailed the contracting company I was with and they said (today) that I can only receive shoubyouteate money if I was with them for 12 months, which I was not.

So I realized the last month of running around talking to this and that person was futile. I searched and found[ this place](https://www.fr-kenpo.or.jp/eng/) and [this place](https://www.hp-kenpo.or.jp/eng/member/outline/retire_a.html) but it seems I am far to late to apply for it. By the time I had to hand in my last shoubyouteate to my previous company it was already to late to sign up to a new insurer.

I can’t seem to find any other place to sign up to, does anyone know one that will accept me? Or do I just try to do uber eats with the small amount of energy I have each day, and hopefully not collapse.
