Does anyone with AGA shed 200 hairs a day ?

[catgreeneyes]

My diffuse hair loss started suddenly a year ago .I have no regrowth from areas where hair has been lost .I was recently diagnosed with AGA due to the pattern of my hair loss(more loss on top than back).Im confused however .Most of the hairs l lose are terminal healthy thick hairs with white bulb.None look like miniaturized vellus hairs and l have no miniaturized hair on my head that l can tell .

-If l did have AGA would the hair not be growing back in but just thinner ?
-If l have aga why did it start suddenly and why am l shedding 200 hairs a day ?is it not ment to be a slow process over many years with minimal shedding ?
-My hair Dr was pretty hopeless .All she did was look at my scalp and hair and from that diagnosed AGA (but couldnt be 100% sure).She didnt look at my scalp or take a biopsy to check for miniaturization if any or do a pull test .
-My scalp also itches like crazy and when l asked if she could look into this she shrugged her shoulders !bloody hopeless !!!!!
