I had 20k in savings and my friend convinced me to start investing at least in S&P 500, as the safest option. I invested 10k and in a month I lost almost 1k. I know for many it’s nothing, but for me, for the first investment, that’s a lot. Regretting my decision haha. What should I do now? Take money back while I only lost 1k and at least keep the rest? Leave them there? First time doing it and I’m scared to lose too much
