I'm sorry to hear about your difficult situation, but at such a difficult time investing in NFT is a way to make things worse. Now your investments will resemble gambling, where the risk will exceed any possible profit, and buying NFT is not the best investment either, especially if you don't know about this industry. Maybe soon the market will recover and you will be able to use cryptocurrencies to improve your financial situation, but if not, then what? Then you will lose even more money.
Investing, regardless of the kind of investment, will always be risky as it is. So i won't advise you to invest for now as you only have few bucks left. Prioritize your needs first, and when you get an extra income, that's the time to invest, but never in NFTs as they will not give you long term profits. For the meantime, just wait for the market to recover, and only then you can sell the coins you are hodling.
