If you switched to Litecoin anticipating a halving pump... you just got dumped on and separated from your precious bitcoins . Don't try to chase your massive BTC losses or you'll lose the little you might have hopefully have left.
Let this be a lesson for people who invest in shitcoins (anything other than BTC ) and follow advice on any of these shitcoins. LTC is a prime example of a coin only in existence to increase BTC bags; look at its history. The next 2 years will be slow bleed to below 0.001 ratio.
