Laid off. Broke. Depressed. & idk how to market my SaaS

I live in a third-world country with a family who's dependent on me. I used to work as a Software Engineer specializing in MERN Stack. I was laid off a month ago, didn't have any saving cos I was already hand-to-mouth, supporting a family of 5 with funding my brother's University fee.I am really depressed and have done nearly everything I knew to market my SaaS products but nothing's working.
Tried:

1. Submitting my product on SaaS directories + on LTD ones (got rejections & some didn't respond),
2. Built in Public (no response),
3. Got Permanently Banned from Reddit (cos I did self-promotion as I wasn't aware - my mistake, i accept),
4. Wrote Articles & submitted on GSC, almost a month has passed & still not indexed,
5. Cold outreach (0 response rate, did personalized outreach, researched about each person + their products & mentioned I'll give free 3 months access)
6. Approached micro-influencers & told them I'll give them commission + other perks (0 response)

I don't know what else to do.
Really losing hope in everything...
