what are these bug bites - please HELP

okay so i have an extreme phobia of small insects crawling on/feeding off my body so im writing this between panic attacks

ive beet noticing bites on my body the past few days and chalked it up to heat rash or mosquitoes cause summer

but i saw this bite that was previously just a little scratch but somehow looks deeper? i dont know if im imagining it but let me know if you know what it is?

and how to treat it ASAP (TEMPORARILY AT HOME bc its 6 am and i dont currently have a car) i have coconut oil? olive oil? apple cider vinegar? there has to be something😭😭😭

also after i can go get things tomorrow and deal with this… how do i? out of the whole apartment bed, my hair and body??? THE FASTEST WAY POSSIBLE i have a final on friday and i wont be able to function like this

THANK YOU IN ADVANCE AND IM SORRY FOR THIS LONG PANICY POST
