Lump sum in February on msci world

I invested 30,000 euros in lump sum last month, which I tried to correct a little with the decline, but I feel like I made a big mistake, having arrived at the wrong time, seeing all the Reddit comments. I don't know if posting here will reassure me or, on the contrary, undermine me. I invested in pea on msci world I can make dca of the 1000 euro and possibly remain 10000 euro also
