Dont worry mate, you are not alone. Take it as a leason and just stop the trading part of investing...
Buy when low and hold until you think the value is high enough... If you turn out to be wrong and it goes down you also need to be able to sell even though its a loss. I see all invested money in crypto as gone either way.. so then I dont get disapointed when things dont go as planned. But to do that you cant really invest any money which you cant afford to loss..
