What are your biggest fears?

So i have severe thanatophobia/ death anxiety which pisses me off because my mind randomly decides when I'm trying to sleep this is the best time to think about all my loved ones dying and that is probably one of the main reasons why i'm sleep deprived, and another one is a specific fear of IVs? idk if that's counted as trypanophobia though, but the size of the needle lwk gives me a panic attack because wym your going to shove it up my vein... and well my fear of IVs originally came from seeing a dude getting an IV before me strapped down and screaming bloody murder while the curtains were drawn so yeah... that's something... and the last one which isn't really a fear but just random intrusive thoughts, which is my liking of yaoi getting discovered because I'd probably be disowned on the spot
