Is VTI really safe? Since the beginning of 2022 it has lost nearly 15%!

I mean i thought VTI was one of the safest places to park money, i can't imagine the pain individual stock holders are suffering this year. What should i do? Sell and cut my losses or keep doing DCA into VTI for the foreseeable future? My horizon is 10+ years but still it hurts psychologically to see your safety nest egg being tear apart by the bear market!
