If I am given a chance to go back to 2020 I would hold my ETH very tight and never let go, when covid was hitting the world at its best I thought it over and I sold 24 ETH which I bought at 120$ each, I never knew I was so damn lucky to buy at that price, learn to hold tight if you believe in a project, there are countless of projects in past years that are way bigger in value right now.
Well, if you really need that money for something I can accept that you sold your holdings but right now you can buy again and wait for another ATH because in my opinion right now the price of ETH is pretty low. Don't regret your decision but make it become one of your experiences so you can keep patience and get higher expectations in the crypto that you hold.
