Are you actually caring for the market or you caring for your future?. I think Mia Chloe has given you a good response, but you have to understand that Bitcoin appreciates over time, as the activities that we do as individuals such as buying, hodling, etc puts the market inorder, and sometimes otherwise. If what you intend on spending on isn't important, then I see no reason why you should sell your Bitcoin, besides your own fraction of Bitcoin as an individual won't affect the market much compare to when a company like microstrategy sells all their portfolio.
You should probably hodl till the last minute where you just have to do it. The future is more important.
