Hi, I Had Dangue Fever Last Month, Was Hospitalized For

hi, I had dangue fever last month, was hospitalized for two weeks, i'm better now, but i have a massive hair fall in two weeks after discharge, i am afraid i am getting bald. I am a lady at the age of 36. Plz guide me how to get my hair back, i am too much stressed out. I don't have half of the hair I had 10 days ago, and it keeps falling more than 500-600 a day
