How do I recover my BitLocker key?

Excuse me, I'm having some trouble accessing my computer and I think I need to recover my BitLocker key. Could you please walk me through the process of how to go about doing that? I'm not very familiar with this sort of thing and would appreciate any guidance you could provide. Are there any specific steps I should follow, or is there a specific website or tool I can use to help me recover my key? Thank you in advance for your assistance.
