I need advice.

guys ive been stressed about this covid sense it began. i have a cough and i feel like im short if breath sometimes but i dont know if its just me overthinking it. My temperature was 37.2 today i and i got scared. my nose seems blocked. my oxygen levels are at 99. i suffer with severe health anxiety. im always overthinking things. i feel a pressure on the top of my head like its being squeezed. and i do have urine infection aswell my doctor checked my urine the other day. i dont know i feel like i want to ask to get tested again.i was tested in may because i thought i had it and it was negative. my little boy is 6. and his been sneezing and of course in panicky about it.. dont want him to be sick. its his birthday sunday and i dont want to feel like this for his birthday. what do u think i should do. maybe the doctor will be annoyed if i ask to be tested again i just dont know.

i dont have a temperature but my nose is blocked and yes my head feel like it being squeezed m neck is so tense and feeling tired no energy i been having this for a a month or so .i think sinuses or allegy i think its to do with the weather hot humidy . i have high blood pressure and that can cause tension headaches .i think you just have to trust the doctors . its helps as long you know you are breathing and your walking and eating your still alive then you dont have to worry .i have anxiety and check your blood pressure
