random low fevers and extreme debilitating anxiety

about last saturday night or so i started feeling feverish (i.e. chills, body aches, sweating), so i took my temperature and was met with 99.8. i struggle with awful awful awful health anxiety. to the point where im too scared to even get checked out for the minor issues that trigger me. so when i saw that reading, i started to stress. i began to take dayquil and let my fever decrease throughout the day but then on the second day i started having a headache. my only symptoms were fever and headache. i googled this and was met with horrifying results. cancer (leukemia, lymphoma), meningitis, amongst other things that scared me to my core. my fever broke on the third day which is the textbook duration of how long a low grade fever should last. but on the day it broke without taking medicine, i still had a mild headache. on the day after it broke, i was perfectly fine. then, after i got back from work, i started having a breakdown. i was screaming crying sobbing pacing around hyperventilating, literally the worst panic attack of my life. after it resided, i checked my temp out of impulse and it was at 100.9 degrees. great another thing to be stressed about it. this was yesterday, and now my temp is averaging around 99.6 and under w/o medication. i am still aware this is a low grade fever which is making me very scared. im so terrified of cancer and im too scared to even get it checked out. that much change would ruin me. and now my mind wont stop yelling at me telling me i have cancer and that every pain in my body is cancer and i just cant stop it. im really hoping this fever is just a "psychogenic fever" which is caused by intense stresss, due to my fever coming back after my panic attack. im really scared, some advice would be great. thanks.
