Am I too financially screwed to ever retire?

I'm 59 years old, live on L.I N.Y Sold my house during the pandemic (my business got crushed) and now I rent rather than own at $3400 per month. 22% of my money is in cash average yield 5.19% 78% is in stocks & S&P funds It all amounts to $680,410 Should I take more risks? How can I ever retire?
