I think you need to think seriously about your risk appetite. You do not have to invest in individual companies to make returns. You do not have to take huge risks. You do not have to beat the market.
Figure out how much risk you can handle, and invest accordingly. That may well be just investing monthly in a world tracker ETF and some bonds.
This forum is not always helpful, do your own research and don’t get fixated on specific companies that may just be ‘meme’ stocks.
Personally it does not sound to me like you are ready to invest in the stock market, as it appears that your risk appetite is too low and that you’d be better served by a cash ISA.
