Thinking of taking my money out the market

Hi guys,

Wonder if anyone is feeling similar.

Whilst I want to retire early, I no longer feel confident in my decision to invest into ETFs monthly. The horizon I see for the stock market feels more uncertain and risky than ever before. I feel that AI, a likely war with Iran (and wider escalation), the fall of the dominance of the dollar alongside further worsening of the economy for working people in the UK makes investing in the stock market an incredible gamble on the future of the economy. Yes, it's always been a risk but the future feels particularly uncertain.

I'm thinking of withdrawing all of my S&S ISA holdings that I've accumulated over 5 years and simply using these funds to overpay my mortgage.

Am I wrong for thinking like this?
