You’ll be fine,shedding is a natural part of a hairs life.The Dut may not even be the cause of your shedding,you can shed due to a change of season.
I know it’s hard but try not to think about it,stop obsessing over it & stop looking in the mirror every damn second because it will only make things worse !!!
You hair wont regrow over night,it will take months but it will come back. Relax,if you can’t handle the pressure shave your hair down to a number 4 or 3 so the shedding wont be as apparent to the eye.
I recently went to a doctor who happened to be a very old,hard of hearing Jewish man.I told him my hair was shedding & he looked at me and said,“Huh? Vat do you mean you are shtng yourself?”
LOL ! At the time I was so depressed because I was shedding hair but when he said that I laughed so hard it raised my spirits.
