How to deal with big stock losses?

I currently do have big losses on 4 stocks that I have chosen to invest in for 3 - 5 years. I haven't held them for that amount of time yet, but I am doubting my decision. I admit that I was greedy and I should have held onto my blue chip stocks last year. I want to move forward, but I'm battling to reach a decisions. I have come up with these three options: 1) Sell and move on 2) Sell portion and hold rest 3) hold My current big losses are ipoe (sofi) , actc (proterra), ai (c3ai), and u (unity). Please advise if you know any of these companies. Thank you in advance.
