This is really bad, sorry for your loss, too bad you learnt your lesson the hard way, I would advice you always avoid fomo and never use more than 30% of your total assets to invest in one project, don't be too greedy and invest 90% of it, thinking it will give you higher returns it's too risky to invest huge amount of money in new projects cause you don't know what the market holds for them, and it's not the end of the road for you, I will suggest you learn how to trade, then maybe you can use this 4 ETH to start trading, just remember this basic strategy "buy low and sell high" and in no time you will recover your money.
