Do not blame yourself because it just normally happens for every individual buying a crypto coin in a lower price and then waiting up for the moment to rise up the price to sell what you have bought to obtain profit. Do not feel too bad on that because no one can literally predict what will be the price movement or the price behavior due to the reason that the price of cryptocurrencies are volatile. I have also experienced the same thing before that I feel too bad for myself of thinking that I have miscalculated or have wrongly predicted things out making me missed an opportunity of obtaining profit but it turns out that after a span of time, I have unexpectedly saw that the price of the token I have purchased risen up enabling me to get a profit from it. You too must have wait a little more longer because if you will sell your token at a lower price to cut your loss, you will no longer be able to regain what you have loss and talking about Litecoin, it is one of the Altcoins I believe that has a capacity and capability to grow just wait and see.
