Feeling demotivated to continue Bitcoin accumulation

Sold over 70% of my Bitcoin I’ve been collecting for years to put money down on a home. It sucks to see a collection like that disappear in an instant. My cost basis was around 66k/coin and I sold for 80k/coin so it was a little profit which is nice but that also means trying to catch back up to my original amount will cost more which adds to the demotivation.
