Not to bash multitasking but can you give me examples of how you prioritize? I have a million and one things to do

(gross exaggeration, it just feels like a million things) and get so overwhelmed and don't know where to start. If I try to do it all, it feels like I am getting nowhere, I even stopped watching TV, (okay reduced watching TV)…
How do you prioritize your different tasks?
Suggestions Please...
