Unemployed and have to pay 80k/month NHI

I recently quit my work, its a contract work actually and i did not continue my contract because i wanted to take a long rest because i was tired and stressed working and planned to use unemployment benefits as a help to pay my rent and my bills on my resting period.

However, i discovered that after unemployment, its mandatory to apply for National Health Insurance(NHI). And when i was employed, my employer pays half of it with a private Health insurance. And it was only 35k/month.

Now, i developed really bad skin allergies after my 1.5 month overseas trip after quitting my work, and its spreading in my whole body like crazy and im itching so much even though i am taking Allegra Fx. So i applied for National Health Insurance. However, i am shocked that i have to pay 80k/month.

Now, there is a 50/50 chance i can only pay 30% which is good. But it depends on the HelloWork judgement for me. If the company laid you off, or the company ended your contract, you can get those reduction. But if its voluntary reason, you cannot. But i hope the mental harassment at work can be an excuse for me to get the 70% reduction because, dang. I do not have any income anymore and i also travelled for more than a month and spend a lot of money. ;( So now, i am just using my not so high savings to live by, because the unemployment benefits i will get will only be paid for the NHI, plus the residence tax. My residence is so high. I just paid 115k this September 1. And i have to pay the same amount again on October 31. Will try to check tomorrow if i can get a reduction.

TLDR:

So sad that being unemployed here in Japan costs you more government expenses than if you are employed. For people like me who thought that quitting jobs and just relying on unemployment benefits to rest, well, you have to pay the whole amount of health insurance now. Plus your pension contribution will be also reduced. Plus paying residence tax.

Anyway, is the 80k/month NHI too high?

Any tips for someone who experienced the same on how to reduce this amount with voluntary contract end, due to mental stress?

Thank you so much for your help.

Update:

I was aware i need to pay for NHI, but did not realize that i have to pay this much. Like i was paying 35k monthly when i have a job. Now i have to pay 80k monthly without a job?! Cruel. Need reduction request here ;(
