S&P thoughts?

Been investing since 2022, CSPX via IBKR, did not really DCA a fixed amount every month but more of accumulating 5K then buying etc etc.

Average cost is about $599 and now current price is $600. Almost wiping out everything earned over past 2 years/2.5 years?

I understand to just hold and will do that. Just starting a convo to see if others are similar / what did I do wrongly?

Thanks
