The best thing you can do whenever you are losing is to sleep. Sleep as much as you can to keep you away from this holy crypto world.
And yes ofc you need to recover yur losses. So how can you do that? And how much time it will take?
In my opinion the better thing to do is invest or trade with coins which are stable.
People always invest in coins which are unstable in expectations of fair advantages(good returns). But that is where you make mistakes.
So in this lose you have learnt a lesson and hope next time be careful while investing into a particular coin.
