Im down 40% and a year’s worth of salary. Should I sell everything and put it into SPY/VOO/VTI?

I started investing in Jan 2021 after my friends told me how easy the stock market was. They started in April 2020 and were saying every thing went up and they had 5x their money in 8-9 months. Thier idol was Cathie Wood. And they called her Mama Cathie. So I jumped into the market the difference being I Peter Lynch was the person who inspired my investing habits. So I invested in what I know and never got into meme or speculative stuff.

So I invested in GOOGL, META, AMZN, NKE, FDX, BLK, F, SPG, DPZ, EXPE, WBD, TGT, DIS, NVDA, AMD, BAC, and MMM. All over the last 2 years and im now down 40%. Should I sell them all for SPY/VOO/VTI. I feel hopefully I thought I was investing in quality companies but I ended up buying them all at what turns out to have been either their 52 week or ATH.
