Some of the coins I'm holding are now down over 80% , will I see something worse than this?

Just checked my portfolio and some coins are down 70% - 80% from the price I bought. This feeling is similar with the one I had in May 2021 but back then we had so many people calling for lengthening cycle and BTC hitting $100k EOY. I had a small hope back then.

​

This year feels a lot worse. Will I see something worse with my portfolio? What happened when I'm down 100% then? Will my coins have zero value? I'm slightly panicking now cos I have never seen them down this bad, probably only 60% and people keep saying "it'll get worse when it's down 80%". It happens now, so what's next? All of my money worth nothing? This is also the first time in over 15 months that my ADA holding is getting closer to make a loss so it's definitely different than May crash, a small correction or whatever it was the past year.

​

I'm definitely holding them, should I just focus on my life and come back in 2023 or something? I just don't see anything recover in 2022 after being in downtrend for months. Other markets are experiencing bad day as well so I have no hope. What u guys thinking? Is holding better than selling at such HUGE LOSE atm?
